Study of the factors of health promotion at an industrial plant]

Using special survey questionnaires industrial problems were identified which directly or indirectly determine healthy lifestyle of workers at the Leningrad spinning factory "Red Thread". Difficulties, efforts and potential opportunities to solve these problems were determined with the assistance of administration and public, and also the reasons for ++shrinking of different authorities from the solution of some problems. The apparent divergences in the assessment of problems by different authorities and the necessary attribution of responsibility for their solution require special instructions for the practice of healthy lifestyle formation.     

Urine melatonin in alcoholic patients: a marker of alcohol abuse?

Ethanol is known to alter central neurotransmission and endocrine functions. Urine melatonin was studied in 10 male chronic alcoholic patients, before and after two weeks of controlled alcohol abstinence, and in sex and age matched healthy controls. In both groups, 24-hour urines were collected in two fractions corresponding to day- (D) (08:00-20:00) and night- (N) (20:00-08:00) time. Urine melatonin was assayed by RIA after methylene chloride extraction. Twenty-four hour urine melatonin levels were calculated adding up D and N values. In patients during alcohol intake, the 24-hour urine melatonin levels were significantly higher than in controls (p = 0.004, Student's t test). A disruption of the physiological ratio between N and D values was also observed, since the higher melatonin levels occurred in the D fraction. In drinking alcoholics, melatonin D values were significantly higher than the D values found in controls (p less than 0.01, Student's t test) and in the same patients after alcohol withdrawal (p less than 0.05). The N/D ratio approximated 1 during alcohol intake and became larger than 1 after alcohol withdrawal, as in the controls. The melatonin data were correlated with the suppressive effects of dexamethasone (DXT) on cortisol secretion evaluated both during alcohol intake and during abstinence. After alcohol withdrawal, the two (out of 10) patients, who remained unresponsive to the DXT suppression test, showed high D melatonin values and a low N/D ratio. These preliminary data indicate that in chronic alcoholism the pattern of urinary "melatonin- like immunoreactivity" is altered.     

Characterization of lymphoid cell populations in bovine lymphosarcomas (“leukosis”) by flow-cytofluorometry

Acridine orange stained cell suspensions from ten cases of bovine lymphosarcoma were analyzed by flow-cytofluorometry. The green DNA-AO fluorescence showed in all cases, but one, two distinct separate lymphoid cell subpopulations. One corresponded to (normal) diploid lymphoid cells, the other had variable aneuploid values. The histograms of the latter cell populations also indicated cells in S- and G₂-phase. Low-angle light scatter histograms did not show a distinct separation between the different cell types, although two maxima could be distinguished. The relative proportions between the two cell populations varied between 20 and 80% with domination of one or the other cell type.There was some conformity to the histological and cytological picture in the ordinary light microscope, although neither a clear distinction in separable cell types nor differential counts was possible.The diploid lymphocyte subpopulation in the tumor might represent an immunoreactive process against the BLV-induced lymphosarcoma.

三黄软膏皮肤用药毒性实验研究

为观察三黄软膏药物外用的安全性 ,进行了动物完整皮肤及破损皮肤长期接触三黄软膏 ,经皮肤渗透对局部及全身产生的毒性和反应的恢复程度 ,用三黄软膏 2g·kg-1、10g·kg-1剂量 (分别相当于 6 0kg人临床用量的 10、5 0倍 )连续对家用兔外用给药4周及停药恢复性观察 2周。结果表明给药期动物的皮肤状况、全身症状、行为活动、摄食、粪便性状、体重增长、血液学均未见明显的毒性反应 ,而高剂量组动物血液生化指标AST、ALT明显增高 ,病理组织学检查时肝水肿明显 ,可见有一定的毒性反应 ;停药期动物的血液生化指标AST、ALT肝组织病理组织学检查恢复正常 ,其他各项指标均未见明显的毒性反应 ,可见该毒性反应是可逆恢复的。表明三黄软膏在临床用药范围内连续使用是比较安全的。     

地塞米松体外诱导宫颈癌细胞株凋亡及其机制的研究

目的 :研究地塞米松 (Dex)体外能否诱导宫颈癌细胞株 (HeLa细胞 )发生凋亡及其机制。方法 :采用透射电镜、DNALadder、流式细胞仪等方法进行凋亡检测 ,用ECLWesternblot方法检测凋亡过程中相关基因表达的变化。结果 :地塞米松体外作用于HeLa细胞后 ,透射电镜观察到了凋亡小体 ;DNALadder法也检测到了凋亡时DNA降解形成的梯带 ;流式细胞仪检测到了细胞凋亡峰 ,且峰值随着处理时间的延长而增高。在凋亡过程中 ,凋亡相关基因bcl 2表达下调 ,而p5 3基因表达无明显改变。结论 :地塞米松体外能诱导HeLa细胞发生凋亡 ,其机制与bcl 2基因的表达下调有关     

性病后非病原体性症状的临床分析

目的了解性病后非病原体性症状的性质特点。方法采用临床会谈、心理咨询、SCL—90、SAS、SOS等相关量表调查测评。结果纳入分析病人134例，首诊均作实验室检查培养，病原体检出率为零，体格检查无器质性病变，符合非病原体性症状诊断。结论此类“症状”实质上是患者因患性病导致心理障碍面出现的综合症，而“症状”并无器质性及病原体因素，医务人员应更新观念，提高自身素质解除患者心理障碍。     

COMMENTS ON THE HOLISTIC ACTION OF ACUPUNCTURE IN VIEW OF ITS INFLUENCE ON NERVE-ENDOCRINE-IMMUNE NETWORK

In the present paper, the author makes some comments on the holistic action of acupuncture from the regulative effect on the nerve-endocrine-immune network, and the close relationship between the nerve-endocrineimmune network and the meridian-collateral system of TOM. The wholism concept of TOM refers to the organism being an integrated entirety, and the regulatory effect of acupuncture on functional activities of the organism relies on the integral connection of the acupoint--meridian-collateral-zangfu-organ system. When stimulated with acupuncture, the human body will brings its potential force into full play in preventing and treating diseases.
