(-)和(+)棉酚对雄大鼠生育力的影响

Racemic, (-) and (+) gossypol, provided by the Department of Organic Chemistry of our institute, was suspended in 2.5% tween 80 solution. Adult male Wistar rats 190～220 g in weight were allotted to 5 groups. Animals in group 1 received 2.5% tween 80 solution as control. Rats in group 2 were treated with racemic gossypol at the dosage of 30 mg/kg for 2 weeks. Animals in group 3 and 4 were given 15 mg/kg of (-) gossypol for 2 weeks and 30 mg/kg of (-) gossypol for 1 week respectively. Rats in group 5 were treated with (+) gossypol at the dosage of 30 mg/kg for 2 weeks.Four weeks from the beginning of gossypol treatment the rats were cohabited with adult females for 7 days. Then the motility of the sperms in the cauda epididymides was estimated The female rats were examined for pregnancy 7 days later.Treatment with (-) gossypol at 30 mg/kg caused significant decreases in body weight of the rats (P<0.05). One of the five rats died 7 days after the last administration, while (+) gossypol and racemic gossypol at the dosage employed had no effect on the body weight. (+) Gossypol at 30 mg/kg for 2 weeks had no effect on the motility of the sperms in the cauda epididymides and no effect on the fertility of the animals: nor was there any effect on the weights of the testis, epididymis, prostate and seminal vesicle. The sperms of the cauda epididymides were found to be dead in the groups treated with 15 and 30 mg/kg of (-)gossypol. Raccmic gossypol given for 2 weeks at 30 mg/kg caused loss of fertility of the male rats which confirmed our previous findings.(?)t may be postulated that (+) gossypol has no antifertility effect nor toxicity at the dosage employed. (-) Gossypol is the active stereoisomer of racemic gossypol.     

The immunosuppressive effect of gossypol in mice is mediated by inhibition of lymphocyte proliferation and by induction of cell apoptosis

Aim： To investigate the immunosuppressive effect of gossypol in mice both in vitro and in vivo. Methods： The in vitro effect of gossypol on the proliferation of lymphocytes isolated from lymph nodes of BALB/c mice was determined by CFSE staining and by an MTS assay. Lymphocyte activation and lymphoblastic transformation were evaluated with immunostaining. Cell apoptosis was detected by Annexin-V and Hoechst 33342 staining. The in vivo immunosuppressive effect of gossypol on the DTH reaction was evaluated using a mouse DTH model induced by 2,4-dinitro-1- fluorobenzene （DNFB）. The thickness of the ears was measured, and the histological changes of the mouse auricles were observed after hematoxylin-eosin staining. The proliferation capacity of lymphocytes from DTH mice was also assayed. Results： In vitro, gossypol could significantly inhibit the proliferation of mouse lymphocytes stimulated with phorbol ester plus ionomycin in a dose-dependent manner. Although the expression of the early activation antigen CD69 was not affected, the lymphoblastic transformation of both T and B lymphocyte subsets was significantly suppressed by gossypol. Moreover, gossypol could induce apoptosis of lymphocytes, and the effect was time- and dose-dependent. In vivo, the DTH reaction in mice was markedly alleviated by gossypol injected intraperitoneally. Lymphocytes from drug-treated DTH mice had a reduced proliferation capacity as compared with lymphocytes from untreated DTH mice. Gossypol treatment also markedly reduced the number of infiltrated lymphocytes in the auricles of DTH mice. Conclusion： Gossypol exhibited immunosuppressive effects in mice, probably by inhibition of lymphocyte proliferation and by induction of cell apoptosis.     

宫腹腔镜联合手术治疗不孕症102例疗效观察

Objective To investigate the role of hysteroscopy combined with laparoscopy in treatment of infertility.Methods 102 patients with infertility treated by hysteroscopy combined with laparoscopy were retrospectively analyzed.Results Of 102 cases of infertility,there were 57 cases with Pelvic adhesions and tubal obstruction,24 cases with endometriosis,12 cases with polycystic ovary syndrome,4 cases with endometrial polyp,3 cases with hysteromyoma and 2 cases with uterus septum.The first three cases were chronic pelvic inflammatory with salpingemphraxis ( 55.88% ), endometriosis Ⅰ -Ⅱ (23.53% ) and polycystic ovary syndrome (11.76% ).The postoperative pregnancy rate was 41.18%, 3 patients with ectopic pregnancy (7.14%) and 4 spontaneous abortion (9.52%).Conclusion Laparoscopy with hysteroscopy played an important role in treatment of infertility.It was an effective method and worthy to be widely used.     

Synergistic effect of combining paeonol and cisplatin on apoptotic induction of human hepatoma cell lines

Aim： To investigate whether paeonol （Pae） has synergistic effects with cisplatin （CDDP） on the growth-inhibition and apoptosis-induction of human hepatoma cell lines HepG2 and SMMC-7721. Methods： The cytotoxic effect of drugs was measured by 3-（4,5-dimethylthiazol-2-yl）-2,5-diphenyl-tetrazolium bromide assay. The coefficient of drug interaction was used to analyze the nature of drug interactions. Morphological changes were observed by acridine orange fluorescence staining. Cell cycle and the apoptosis rate were detected by flow cytometry. Bcl-2 and Bax expression were assayed by immunohistochemical staining. Results： Pae or CDDP had antiproliferative effect on the 2 cell lines in a dose-dependent manner, with different sensitivities to drugs. More interestingly, a synergistic inhibitory effect on the viability of the 2 cell lines was observed after treatment with a combination of Pae （15.63, 31.25, and 62.5 mg/L） with various concentrations of CDDP. Further study showed typical morphological changes of apoptosis if the cells were exposed to the two agents for 24 h. The apoptotic rate of the cells with combination treatment was significantly higher than that of cells treated with Pae or CDDP alone. The expression of Bcl-2 decreased and that of Bax increased in the treated groups, especially in the combination group, with the ratio of Bcl-2/Bax decreasing correspondingly. Additionally, a combination of Pae with CDDP resulted in a stronger S phase arrest, compared with Pae or CDDP alone. Conclusion： Pae, in combination with CDDP, had a significantly synergistic growth-inhibitory and apoptosis-inducing effect on the 2 human hepatoma cell lines, which may be useful in hepatoma treatment.     

The therapeutic effect of Balanophora polysaccharide on acetic acid gastric ulcer in rats and its mechanism; [蛇 ? 多糖对大鼠乙酸型胃溃疡的治疗作用 ? 机制]北大核心CSCD

Aim To study the therapeutic effect of Balanophora polysaccharide(BPS)on gastric ulcer(GU)induced by acetic acid in rats and to investigateits mechanisms. Methods Sixty male SD rats were randomly divided into sham-operated group, GU model group, omeprazole positive group(3.6 mg·kg-1), and low, medium and high dose of BPS treatment groups(100, 200 and 400 mg·kg-1). The GU model group was prepared by acetic acid cautery method, and the morphology and pathological changes of ulcers were observed by visual observation combined with HE staining, and the ulcer area and inhibition rate were measured and calculated; superoxide dismutase(SOD)activity, malondialdehyde(MDA)content and glutathione peroxidase(GSH-PX)activity were measured by enzymatic assay; tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)content were detected by ELISA. The expression levels of epidermal growth factor(EGF)and epidermal growth factor receptor(EGFR)were measured by immunohistochemistry staining and Western blot. Results Compared with the sham-operated group, obvious ulcer damage was seen in the model group. Compared with the model group, the BPS-treated group showed a significant reduction in ulcer area, an increase in SOD and GSH-PX activity and EGF and EGFR expression levels, and a significant decrease in MDA, TNF-α and IL-6 content. Conclusions BPS has a therapeutic effect on GU in rats, and its mechanism may be related to the inhibition of oxidative stress, suppression of inflammatory stimuli and promotion of regenerative repair of gastric mucosa. © 2023 Publication Centre of Anhui Medical University.

阿片样物质介导多潘立酮和西沙必利对小鼠的镇痛作用

To study the anti-nociceptive effect of domper-idone and cisapride in mice. METHODS: Initially, the effect of these drugs on motor activity was tested using rotarod. The anti-nociception was tested using chemical and mechanical assay. In the chemical assay, the number of abdominal constrictions either in the saline treated animals or in the domperidone/cisapride (1, 5, or 10 mg/kg either po or ip) treated mice, were recorded for a period of 30 min after acetic acid challenge (10 mLAg, of 0.6 % acetic acid ip). In the tail clip assay, the time taken by the mouse to make attempts to dislodge the bulldog clamp placed at the tail (reaction time) was recorded with a cut off time of 30 s. The role of opioid pathways was examined by pretreating the animals with naloxone (1 mg/kg, ip) 30 min prior to domperidone and cisapride. RESULTS: Domperidone and cisapride, both reduced the number of abdominal constrictions when given orally or intraperitoneally. Domperidone (5 mg/kg) inhibited it to the extent of 57.0 % a     

HD-03对实验性肝硬化的抑制(英文)

AIM; To investigate the protective effect of HD-03 in experimental cirrhosis following chronic intoxication with thioacetamide (TAA). METHODS; The effect of HD-03 (750 mg/kg po) was studied in rats following TAA-induced intoxication (50 mg/kg po) for a period of 90 d. HD-03 was administered as an aqueous suspen-sion . Levels of biochemical markers indicative of hepa-totoxicity were assessed in serum and liver. Histopatho-logical evaluation of liver was also carried out to find out the protective effect of HD-03 following TAA-induced chronic intoxication. RESULTS; Administration of TAA at a dose of 50 mg/kg po for 90 d resulted in a sig-nificant derangement of serum [ serum glutamic pyruvate transaminase ( SGPT), serum glutamic oxaloacetate transaminase (SGOT) , alkaline phosphatase (ALP), al-bumin and bilirubin] and hepatic (triglycerides, protein, hydroxyproline, collagen and glycogen) biochemical pa-rameters. Histopathological evaluation of liver sections following TAA-intoxication showed necrosis and     

Palmitic acid induces autophagy in hepatocytes via JNK2 activation

Aim： Free fatty acid-induced lipotoxicity plays a crucial role in the progression of nonalcoholic fatty liver disease （NAFLD）. In the present study we investigated the effects of a high-fat diet and free fatty acids on the autophagic process in hepatocytes in vivo and in vitro and the underlying mechanisms.
Methods： LC3-II expression, a hallmark of autophagic flux, was detected in liver specimens from patients with non-alcoholic steatohepatitis （NASH） as well as in the livers of C57BL/6 mice fed a high-fat diet （HFD） up to 16 weeks. LC3-II expression was also analyzed in human SMMC-7721 and HepG2 hepatoma cells exposed to palmitic acid （PA）, a saturated fatty acid. PA-induced apoptosis was detected by Annexin V staining and specific cleavage of PARP in the presence and absence of different agents.

Results： LC3-II expression was markedly increased in human NASH and in liver tissues of HFD-fed mice. Treatment of SMMC-7721 cells with PA increased LC3-II expression in time- and dose-dependent manners, whereas the unsaturated fatty acid oleic acid had no effect. Inhibition of autophagy with 3MA sensitized SMMC-7721 cells to PA-induced apoptosis, whereas activation of autophagy by rapamycin attenuated PA-induced PARP cleavage. The autophagy-associated proteins Beclin1 and Atg5 were essential for PA-induced autophagy in SMMC-7721 cells. Moreover, pretreatment with SP600125, an inhibitor of JNK, effectively abrogated PA-mediated autophagy and apoptosis. Specific knockdown of JNK2, but not JNK1, in SMMC-7721 cells significantly suppressed PA-induced autophagy and enhanced its pro-apoptotic activity; whereas specific knockdown of JNK1 had the converse effect. Similar results were obtained when HepG2 cells were tested.

Conclusion： JNK1 promotes PA-induced lipoapoptosis, whereas JNK2 activates pro-survival autophagy and inhibits PA lipotoxicity. Our results suggest that modulation of autophagy may have therapeutic benefits in the treatment of lipid-related metabolic diseases.     

棉酚对离体兔心的失钾作用及其可能机理

Since 1972 gossypol, a biologically active constituent of cotton seed and cotton root bark, was shown to have a potent spermatocidal effect in man. Glinical trials pointed out that occasional cases of hypokalemia and hypokalemic paralysis might happen in the course of gossypol administration. Little was known concerning the intrinsic relationship between gossypol and such hypokalemias.The authors indicated that in isolated rabbit heart brief perfusion with Lock's solution containing gossypyl 2 mg/l could induce a significant loss of the potassium content of the left ventricular myocardium, together with a drastic depression of its contractility. These actions were reversed when Mg²⁺ (2～4 me/l) had been added beforehand to the perfusion solution. It is suggested that the potassium-depleting (and negative inotropic) effect of gossypol on the isolated heart might be the consequence of its possihle inhibitory action on Na-K-ATPase (and/or other Mg-dependent enzyme systems involved in energy metabolism), thus interfering in the active potassium transport.     

醋酸棉酚对雌性大鼠的抗早孕作用

大鼠于妊娠第6～9天,喂以醋酸棉酚80 mg/kg/d, 有明显的抗早孕作用。皮下注射孕酮5 mg/d或hCG 25 IU/d可拮抗醋酸棉酚的抗早孕作用。醋酸棉酚80 mg/kg/d对去卵巢后给以外源性雌酮和孕酮以维持妊娠的大鼠无抗早孕作用。正常妊娠大鼠,给醋酸棉酚后,血清孕酮水平下降,妊娠中止,若同时注射hCG,孕酮水平回升接近对照动物的水平,药物抗早孕作用消失,但仍低于单给hCG组大鼠血清孕酮水平,说明醋酸棉酚可阻断hCG促黄体分泌孕酮的作用,这可能是醋酸棉酚抗早孕作用的主要机理之一。

Effect of 1,25-dihydroxyvitamin D3 on the female reproductive system in rats.

Parenteral application of the active metabolite of vitamin D3, 1,25-dihydroxyvitamin D3, has been anticipated to have remarkable efficacy in secondary hyperparathyroidism. However, in a reproduction seg. I study in rats, poor reproductive performance was reflected in a decrease in the number of matings, implantations and live births. These changes were though reversible after treatment with the compound was discontinued. In order to clarify the mechanism of these reversible toxicities, the following were examined in female rats treated with the D3 metabolite: 1. effect on the estrous cycle (no treatment for 2 weeks, treatment for 3 weeks and recovery for 2 weeks), and 2. effect on the maintenance of pregnancy (treatment for 2 weeks before mating and during the gestation period). In both groups, the levels of calcium, calcitonin, PTH and progesterone in serum were measured, and histopathological examination of the thyroid, parathyroid, ovary and uterus was carried out. The following results were observed: 1) disturbance of the estrous cycle, 2) hypofunctional changes in the corpus luteum in the ovary, and the epithelium, endometrium and uterine gland in the uterus with a decrease in the serum progesterone level and 3) hypercalcemia with a decrease in calcitonin or PTH levels in serum with morphological changes including atrophy and cyst-formation in the parathyroid. However, the above changes were reversible, and recovery was observed after administration of the compound was discontinued. These results indicate that the hypercalcemia caused by 1,25-dihydroxyvitamin D3 disrupts endocrinological homeostasis which in turn temporarily disrupts the female reproductive system. Furthermore, it was suggested that 1,25-dihydroxyvitamin D3 itself directly influences on endocrinological organs (hypothalamus, pituitary, parathyroid and thyroid) and reproductive organs (ovary and uterus).     

Effect of dietary co-administration of sodium selenite on sodium arsenite-induced ovarian and uterine disorders in mature albino rats.

The subchronic treatment of mature female Wistar-strain albino rats in diestrous phase with sodium arsenite at a dose of 0.4 ppm/100 g body weight/rat/day via drinking water for period of 28 days (seven estrous cycles) caused a significant reduction in the plasma levels of leutinizing hormone (LH), follicle-stimulating hormone (FSH), and estradiol along with a significant decrease in ovarian activities of delta five, 3 beta-hydroxysteroid dehydrogenase (Delta5,3beta-HSD), and 17 beta-hydroxysteroid dehydrogenase (17beta-HSD) followed by a reduction in ovarian and uterine peroxidase activities. A significant weight loss of the ovary and uterus was also observed after this treatment, along with a prolonged diestrous phase and a high accumulation of arsenic in the plasma and these organs. Moreover, sodium arsenite was also responsible for ovarian follicular and uterine cell degeneration characterized by a high number of regressing follicles and a reduction in the uterine luminal diameter, respectively, in comparison with the controls. A dietary supplementation of sodium selenite at the dose of 0.6 mg/100 g body weight/rat/day for a period of 28 days along with arsenic treatment minimized the gonadal weight loss significantly and increased the activities of the ovarian steroidogenic enzymes as well as the ovarian and uterine peroxidase at the control level. Selenium was also able to increase the plasma levels of LH, FSH, and estradiol toward the control level. Vaginal smears showed normal estrous cyclicity in sodium selenite-supplemented arsenic-treated rats along with lower arsenic levels in the plasma and gonadal tissue in comparison with arsenic-only-treated rats. Histological sections of ovary and uterine tissues in the control and experimental groups confirmed that sodium selenite supplementation was able to prevent arsenic-induced histopathological changes in the ovary and uterus. Plasma levels of norepinephrine and dopamine in the midbrain and diencephalon decreased significantly, whereas the serotonin level was increased significantly after 28 days of sodium arsenite treatment. All of these parameters were, in most cases, unchanged from the control level when sodium selenite was co-administered with sodium arsenite. Arsenic intoxication was also associated with increased liver weight and elevation in the activities of hepatic and renal acid phosphatase, alkaline phosphatase, and transaminases, but selenium co-administration was not able to change these toxic effects of arsenic. The results of our experiments indicate the significant protective action of sodium selenite on arsenic-induced toxicity in the female reproductive system, while there was no significant protective effect of selenium on arsenic-induced toxicity in other organs.     

Cigarette smoke inhibits recruitment of bone-marrow-derived stem cells to the uterus

Cigarette smoking leads to female infertility and a decreased incidence of endometriosis. Bone marrow derived stem cells are recruited to uterine endometrium and endometriosis. The effect of cigarette smoking on stem cell recruitment to any organ is uncharacterized. We hypothesized that bone marrow-derived mesenchymal stem cell recruitment to the uterus and differentiation would be diminished by cigarette smoke. We used human mesenchymal stem cells (hMSC) in vitro and a mouse model of cigarette smoke exposure. After myeloablation female C57BL/6J received bone marrow cells from males. Mice were exposed to room air or smoke from unfiltered cigarettes. Immunofluorescence and Y-FISH was performed on uterine sections. In vitro hMSCs were treated with 8-Br-cAMP to induce endometrial cell differentiation with or without cigarette smoke extract (CSE) and decidualization assessed morphologically and by prolactin expression. After 4 weeks the total number of Y-chromosome cells in the uterus was reduced by 68% in the smoke exposed mice. Both leukocytes and bone marrow derived endometrial cells were reduced by 60% and 73%, respectively. Differentiation of bone marrow derived cell to endometrial epithelial cells was reduced by 84%. hMSC treated with CSE failed to show cytological characteristics of decidualization. mRNA levels of the decidualization marker prolactin were decreased by 90% in CSE treated cells. Smoking inhibits both recruitment of bone marrow derived stem cells to uterus and stem cell differentiation. Inhibition of stem cells recruitment may be a general mechanism by which smoking leads to long term organ damage through inability to repair or regenerate multiple tissues.

Effect of estradiol dipropionate on uterine and vaginal glycogen content of Parkes (P) mice

Administration of estradiol dipropionate (20 micrograms/day: for 7 days) to ovariectomized (7 days) mice produced about three fold increase (180%) in uterine glycogen content while approximately four fold decrease (76%) in vaginal glycogen as compared to their control values. Differences in glycogen content after 7 and 14 days of ovariectomy were statistically insignificant in both the organs. Although estradiol dipropionate had a great effect on the glycogen content of uterus and vagina but this effect remained more or less unchanged after causing alteration in duration (7 and 14 days) of estradiol dipropionate treatment in relation to different time intervals (7 and 14 days) after ovariectomy. So there was no time dependent response in uterine and vaginal glycogen content after 7 days onwards either in relation to ovariectomy or estradiol dipropionate treatment. The opposite trend (increase in uterus and decrease in vagina) of glycogen content in response to estradiol dipropionate may be possibly due to a greater accumulation (than utilization) in uterus while greater consumption (than accumulation) in vagina.     

Effect of mancozeb on ovarian compensatory hypertrophy and biochemical constituents in hemicastrated albino rat

Mancozeb a carbamate fungicide was administered orally at doses of 500, 600, 700, and 800 mg/kg/day to normal hemicastrated virgin rats for 15 consecutive days to examine the effect on ovarian hypertrophy. Sham-operated and hemicastrated control rats were administered a similar quantity of olive oil. The vaginal smear and body weight of the rats were recorded daily and rats were sacrificed on the Day 16. The ovary, uterus, kidney, adrenal, spleen, liver, lungs, heart, thymus, and thyroid were removed and weighed. The left ovary from each animal was serially sectioned and stained for histologic studies. The hemicastrated control rats revealed a significant increase in relative ovarian weight with 66.3% hypertrophy. Treatment with 700 and 800 mg/kg/day mancozeb revealed a decrease in ovarian hypertrophy with 28.2 and 22.8% hypertrophy, respectively. There was no significant change in the number of estrous cycles and duration of each phase of the estrous cycle with 500 mg/kg/day mancozeb. However, there was a decrease in the number of estrous cycles, duration of proestrus, estrus, and metestrus with concomitant significant increase in the duration of the diestrus phase with 600, 700, and 800 mg/kg/day mancozeb treatment. There was a significant decrease in the number of healthy follicles with concomitant increase in the number of atretic follicles at higher doses of mancozeb. There were no significant changes in the body and organ weight with 500, 600, 700, and 800 mg/kg/day of mancozeb. The levels of protein, glycogen, total lipid, phospholipid, and neutral lipid were elevated in the liver, uterus, and ovary after hemicastration. Protein, glycogen, total lipid, phospholipid, and neutral lipid were not significantly changed in the liver, uterus, and ovary after 500 mg/kg/day mancozeb. However, treatment with 600, 700, and 800 mg/kg/day mancozeb showed a significant decrease in the levels of protein, glycogen, total lipid, phospholipid, and neutral lipid in the liver, uterus, and ovary, with the exception of liver total lipid and uterine glycogen. In addition to the decrease in the compensatory ovarian hypertrophy, mancozeb treatment reduced the number of healthy follicles with a concomitant increase in the number of atretic follicles. This finding plus disruption of the estrous cycle may be due to a direct effect on the ovary or the hypothalamo-hypophysial-ovarian axis.
