A series of preliminary studies was carried out to evaluate the antinociceptive (pain relief) activity of the aqueous extract of Corchorus olitorius L. leaves (COAE) and to determine the influence of temperature and opioid receptors on COAE activity using the abdominal constriction and hot plate tests in mice. COAE, at concentrations of 10, 25, 50, 75, and 100%, showed both peripheral and central antinociception that are non-concentration- and concentration-dependent respectively. The peripheral activity was clearly observed at a concentration of 25% and diminished at a concentration of 100%, while the central activity was observed at all the concentrations of COAE used. Furthermore, the insignificant results obtained indicated that this peripheral activity (at concentrations of 25 and 50%) was comparable to that of morphine (0.8 mg/kg). Pre-heating COAE at a temperature of 80°C and 100°C, or 60°C and 80°C was found to enhance its peripheral and central antinociception respectively. Pre-treatment with naloxone (10 mg/kg), a general opioid receptor antagonist, for 5 min, followed by COAE, was found to completely block its peripheral, but not central, antinociceptive activity. Based on this observation, we conclude that the antinociceptive activity exhibited by C. olitorius is enhanced by the increase in temperature and may be mediated peripherally, but not centrally, at least in part, via an opioid receptor. 相似文献

The insulin tolerance test (ITT) is a standard growth hormone (GH) provocative test to distinguish children with normal variant short stature (NVSS) from those with GH deficiency (GHD). We reviewed ITTs retrospectively in 52 short children using peak GH concentration of 7 ng/ ml as a cut-off level for GHD (peak GH <7 ng/ ml) and NVSS (peak GH > or =7 ng/ml). The average insulin dosage was 0.1 U/kg in children with NVSS and 0.08 U/kg in GHD. Hypoglycemia was achieved in all cases with an average plasma glucose nadir of 1.8 mmol/l (32 mg/dl) occurring between 15 and 45 min following administration. The average peak GH concentration was 12 ng/ml, occurring at 30-90 min. There were no serious adverse effects from the ITT. We conclude that the appropriate duration of ITT should be 90 minutes. The appropriate timing to obtain samples for plasma glucose level is at 0, 15, 30, 45, 60, and 90 min, and for GH concentrations at 0, 30, 45, 60, and 90 min. The shortened duration of ITT to 90 min will reduce the time spent and also the financial cost for unnecessary samples, while still ensuring a correct diagnosis for the patients. 相似文献

We report on an infant with double trisomy 48,XXX, + 18. She presented with manifestations of trisomy 18: prominent occiput, microphthalmia, small mouth, micrognathia, malformed ears, congenital heart defect, overlapping fingers, talipes equinovarus, and rockerbottom feet. An extra palmar crease was present only on the right hand. This patient was alive at 12 months. The clinical manifestations are compared with those of 10 previosly reported cases. © 1994 Wiley-Liss, Inc. 相似文献

A field survey was conducted in 4 primary schools in Nakhon Si Thammarat Province, southern Thailand. By Sasa modified Harada-Mori cultivation method, 1.8% of the schoolchildren were found to be infected with Strongyloides stercoralis, and 25.1% had hookworm infection. By Kato's thick smear method, the overall prevalence of soil-transmitted helminths was 46.8%, being Trichuris trichiura 28.5%, hookworm 18.0%, and Ascaris lumbricoides 5.7%. Fecal examination, performed by Kato's thick smear and culture method, indicated that the prevalence of hookworm infection was 26.9%. The prevalence in the present study was very much lower than many previous reports in the past decade. This may indicate the partial success of the parasite control project in Thailand by mass treatment, improving the sanitation and personal hygiene of the people in the endemic area. In light infection with Trichuris, albendazole administered at a dosage of 200 mg daily for 3 days showed a 48.7% cure rate. When mebendazole was given at 100 mg twice daily for 3 days, its effectiveness was 88.5%. A lower cure rate was obtained (70.0%) in moderate to heavy infection. 相似文献

Crude ethanol and water extract of leaves and barks from Cassia alata were tested in vitro against fungi, (Aspergillus fumigatus and Microsporum canis), yeast (Candida albicans) and bacteria (Staphylococcus aereus and Escherichia coli). C. albicans showed concentration-dependent susceptibility towards both the ethanol and water extracts from the barks, but resistant towards the extracts of leaves. The degree of susceptibility varied, the water extract from barks showed bigger inhibition zone than the ethanol extracts (12-16 and 10-14 mm, diameter respectively). The growth of Aspergillus fumigatus and Microsporum canis were not affected by all types of the plant extracts. Results were comparable to standard antifungal drug Tioconazole (18 mm diameter) at equivalent concentration. The anti-bacterial activity of C. alata extracts on S. aureus was detected with only the leaves extracts using water and ethanol. The water extract exhibited higher antibacterial activity than the ethanol extract from leaves (inhibition zones of 11-14 and 9-11 mm, respectively). E. coli showed resistance to all types of extracts. Based on the current findings, it can be concluded that this plant has antimicrobial activity, which is as potent as standard antimicrobial drugs against certain microorganisms. 相似文献

Ethnopharmacological relevance
Orthosiphon stamineus has been used in traditional medicine for centuries especially to treat diseases of the urinary system.Aim of the study
To investigate the diuretic activity, to elucidate its possible mechanism and to evaluate the renal effects of Orthosiphon stamineus extract.Materials and methods
Water extracts were administered orally at doses of 5 and 10 mg/kg to Sprague–Dawley rats and the control groups were given commercial diuretic drugs either furosemide or hydrochlorthiazide at 10 mg/kg. Urine volume, urine pH, urine density and urine electrolytes were determined every hour for 4 h. Blood was assayed for glucose, albumin, blood urea nitrogen (BUN) and creatinine.Results
O. stamineus extract exhibited dose-dependent diuretic activity. However, excretion of Na+ and Cl− was not markedly elevated, but urinary excretion of K+ was significantly increased. O. stamineus extracts slightly increased the serum BUN, creatinine and blood glucose level. Although these levels were statistically significant when compared to control, these levels were still within normal range.Conclusions
O. stamineus exhibited diuretic activity, but was less potent than furosemide and hydrochlorothiazide. Care should be taken when consuming this herb as slight increase of kidney function enzymes was recorded. 相似文献58.
Background
Disorders of sex development (DSD) is a group of sexual differentiation disorders resulting in genital anomalies with defects in gonadal hormone synthesis and/or incomplete genital development. These conditions result in problems concerning the sex assignment of the child. This study aims to describe the clinical features, diagnosis and management of children with DSD in southern Thailand.Methods
The medical records of 117 pediatric patients diagnosed with DSD during the period of 1991–2011 were retrospectively reviewed.Results
Disorders of sex development were categorized into 3 groups: sex chromosome abnormalities (53.0%), 46,XX DSD (29.9%) and 46,XY DSD (17.1%). The two most common etiologies of DSD were Turner syndrome (36.8%) and congenital adrenal hyperplasia (29.9%). Ambiguous genitalia/intersex was the main problem in 46,XX DSD (94%) and 46,XY DSD (100%). Sex reassignment was done in 5 children (4.3%) at age of 3–5 years: from male to female in 4 children (1 patient with congenital adrenal hyperplasia, 1 patient with 45,X/46,XY DSD, and 2 patients with 46,XX ovotesticular DSD) and from female to male in 1 patient with 46,XX ovotesticular DSD. Of the total 20 children with 46,XY DSD, 16 (80%) were raised as females.Conclusion
Management of DSD children has many aspects of concern. Sex assignment/reassignment depends on the phenotype (phallus size) of the external genitalia rather than the sex chromosome. 相似文献59.

Purpose
The prevalence of both hypertension and obstructive sleep apnea (OSA) are increased in patients with age greater than 60 years. We studied the clinical differences of OSA in hypertensive patients with age greater or less than 60 years. In addition, rate of OSA-induced hypertension in Thai population is limited.Methods
We retrospectively reviewed medical records of patients treated at the hypertension/sleep clinic at Srinagarind Hospital, Khon Kaen University, between 2010 and 2011. The inclusion criteria used were hypertensive patients who had at least one symptom of OSA and had been tested for the sleep study. Rate and clinical features of OSA were studied and categorized by age of 69 years. Factors associated with likelihood of having OSA in hypertensive patients age over 60 years were identified by multiple logistic regression analysis.Results
During the study period, 49 patients met the criteria. Of those, 42 patients (85.71 %) had an apnea–hypopnea index (AHI) of more than 5/h. The average AHI was 22.22?±?13.86 times/h. The common symptoms of OSA were snoring (100 %), daytime sleepiness (28.57 %), unexplained nocturia (28.57 %), and gastroesophageal reflux disease (28.57 %). The numbers of patients with age less than 60 years and more than 60 years were 20 and 22 cases, respectively. Most patients (88.10 %) had well-controlled blood pressure level. Only BMI was significantly associated with OSA-induced hypertension in patients aged over or equal to 60 years. The adjusted odds ratio was 0.743 (0.560, 0.985).Conclusions
OSA is very common in Thai hypertensive patients aged 40–70 years who have at least one symptom of OSA. Lower BMI is a predictor of obstructive sleep apnea in elderly Thai hypertensive patients 相似文献60.

This is the first population‐based study in Thailand on the prevalence of congenital limb defects (CLD). Data were obtained from recently established birth defects registries in three southern Thailand provinces during 2009–2013. Entries in the birth defects registries included live births, stillbirths after 24 weeks gestational age, and terminations of pregnancy following a prenatal diagnosis of fetal anomaly. The total of 186 393 births recorded included 424 CLD cases, giving an average prevalence of 2.27 per 1000 births (95% CI, 2.05–2.49). The most common CLD was talipes equinovarus (44.1%), followed by polydactyly (13.9%) and syndactyly (9.4%). The prevalence significantly increased with maternal age from 1.81 in mothers aged <30 years to 2.75 in mothers 30 to < 35 years, and to 2.94 in mothers ≥35 years (P = 0.004). Overall 9.4% of the CLDs were syndromic CLD, again with significantly greater percentages in pregnant women aged ≥35 years than the non‐syndromic CLD (32.5% vs 17.5% respectively, P = 0.03). In conclusion, the overall prevalence of CLD in the 3 southern Thailand provinces examined was 2.27 per 1000 births, and syndromic CLD was significantly higher in pregnant women aged ≥35 years than younger pregnant women. 相似文献
