A study was carried out for purpose of grasping the status of bacteriological contamination of the public wells in Iri city, during the period from 1 to 15 August, 1974. Coliform groups were detected by membrane filter method and physical conditions of the well were checked. 1. The households which used the piped water occupied 70.8 per cent (11,907 households) out of total households Iri city. 2. Temperature of the well water was 38 out of 50 samples (72.0%) with 12.1 to 16.0 degrees C and 9 wells with 10.1 to 12.0 degrees C. 3. The pH values range of the well water was 6.0 to 7.9, 11 cases of 22.0 per cent less than 6.5 and 8 cases of 16.0 per cent more than 7.5. 4. The residual chlorine was found at 15 samples (30.0%) contained 0.1 to 0.5ppm, 9 samples (18.0%), 0.6 to 1.0 ppm after 24 hours of chlorination. 5. Coliform groups were found at 49 out of 50 samples (98.0%) before chlorination when 100ml well waters was tested by membrane filter technique and 15 wells(30.0%) were potable for drinking within 24 hours after chlorination. 6. Coliform groups positive were 23 out of 26 samples (88.5%) with no residual chlorine, 12 out of 16 samples (80.0%) with 0.1 to 0.5ppm and none out of 9 with 0.6 to 1.0ppm.

BACKGROUND:Stem cel transplantation is a promising treatment of advanced liver disease, and adipose-derived mesenchymal stem cel s have become another kind of popular cel s fol owing bone marrow mesenchymal stem cel s.
OBJECTIVE:To investigate the influence of adipose-derived mesenchymal stem cel transplantation on blood biochemical indices of liver cirrhosis rats.
METHODS:Sixty rats were equal y randomized into normal control, model and cel transplantation groups. Model rats of liver cirrhosis were made in the latter two groups through intragastric administration of carbon tetrachloride. One week after successful modeling, rats were given intraperitoneal injection of adipose-derived mesenchymal stem cel suspension in the cel transplantation group, and given normal saline in the other two groups.
RESULTS AND CONCLUSION:Compared with the normal control group, the model group showed a significant increase in the levels of alanine aminotransferase, aspartate aminotransferase, total bilirubin, total protein in liver tissues, serum level of malondialdehyde, 15-minute indocyanine green retention rate and degree of hepatic fibrosis, and a significant decrease in serum albumin level, serum albumin/globulin, levels of glutathione peroxidase and cyclic guanosine monophosphate in liver tissues. On the contrary, these indicators were al improved in the cel transplantation group compared with the model group.
Moreover, CM-Dil-positive cel s were visible in the liver tissue of rats undergoing adipose-derived mesenchymal stem cel transplantation. Al these findings indicate that adipose-derived mesenchymal stem cel transplantation can reduce liver cirrhosis in rats by acting on blood biochemistry levels.

AIM:To study the sedation, diuresis and anticoagulation effects of Ji-Ming-San (JMS) in animal models for exploring the circadian variations of the dosing action and verifying the rationality of administering JMS on special time. METHODS: The sedation effect and circadian difference were determined by observing the time session of ambulation, raising double-forefoot test and autonomic activity of model mice. The diuretic effect and the circadian variation in rats were examined by metabolic cage test while the anticoagulation and the circadian change were observed by glass test. RESULTS: JMS produced significant sedation effect by reducing time session of ambulation, raising upper limbs frequencies/time and autonomic activity and the built-in rhythm with autonomic activity disappeared after JMS administration. JMS had satisfactory diuretic effect and total urinary output in water-loaded rats was increased after dosing. The diuretic effect of dosing showed a circadian rhythm with more significant output during the night than that during the daytime. Also, JMS prolonged the clotting time significantly and the action exhibited circadian difference. As compared with administration at the night, the clotting time was more prolonged at the daytime. CONCLUSION: JMS can produce obvious sedation, diuresis and anticoagulation effects with varied circadian rhythm. The findings suggest that the effect of administering JMS is better at the end of rest phase than other time session.

There have been increasing reports on liver injury induced by traditional Chinese medicine (TCM) and natural medicine in recent years. The risk of liver injury induced by TCMs has attracted more attention at home and abroad. In this paper,epidemiologic characteristics,risk factors,clinical features of TCMs induced liver injury were discussed. The myth about research and safety evaluation of TCMs induced liver injury was analyzed. Based on the property of TCMs and characteristics of their clinical use,this paper proposed the priorities of basic and clinical safety evaluation of TCMs induced liver toxicity. It is hoped that this study may provide reference for scientific evaluation of liver toxicity of TCMs.

AIM:To observe effects of Jiming Powder(Semen arecae,Pericarpium citri reticulatae,Fructus Chaenomelis,Fructus Evodiae,Folium Perillae,Radix Platycodonis,and Rhizoma Zingiberis recens) on anticoagulation and hemorheology and on the circadian variations in order to verify the rational practice of timing administering the drug by our ancestors. METHODS:The effect of Jiming Powder on clotting time(CT) was observed by using glass-tube method in mice. Quick test was used to determine the prothrombin time(PT) and circadian variations in rats. The experimental animal models of blood stasis syndrome were prepared by subcutaneous injection of adrenaline in combination with ice water bath for observing the effect of Jiming Powder on hemorheology in such types of animals,and the maximum rate of platelet aggregation was determined by method of Born turbidimetry. RESULTS:Jiming Powder could significantly delay CT and PT characteristic of circadian rhythm. As compared with the administration at daytime,CT and PT were greatly prolonged during the night. Besides,the hemorheological parameters were improved markedly in blood,plasma and fibrinogen viscosity,which suggested that the drug administration was more effective during the night than daytime. Also,the findings showed that Jiming Powder could prevent platelet aggregation induced by adenosine diphosphate. CONCLUSION:Jiming Powder plays a role in anticoagulation and improves the indication of hemorhelogy in the blood-stasis rats model,showing dosing time-dependent.

Objective To investigate the protective effects of Xuebijing(XBJ)on the injury of vascular endothelial cells(VEC)induced by lipopolysaccharide (LPS),and to study the mechanisms of the production of nitric oxide (NO)and the expressions of inducible nitric oxide sytnhase (iNOS)and signal transduction under XBJ intervention condition.Methods The cultured VEC were divided into control group, LPS (1 mg · L-1 )group, LPS (1 mg·L-1)+XBJ(25 g·L-1)group,LPS(1 mg·L-1)+pyrrolidine dithiocarbamate(PDTC,20μmol·L-1) group;XBJ and PDTC were administrated 1 h before incubation of with LPS.Western blotting method was used to detect the expressions of iNOS and NF-κB p65 protein.The level of NO in the supernatant was measured by Griess reagent.Results Comparaed with control group,the NO level and the expression levels of iNOS protein and NF-κB p65 protein in VEC in LPS group were significantly increased(P<0.01).Compared with LPS group,the NO level and the expression levels of iNOS protein and NF-κB p65 protein in VEC in LPS+XBJ group were significantly decreased (P<0.05 or P<0.01);the NO level and the expression levels of NF-κB p65 protein and iNOS protein in VEC in LPS+PDTC group were significantly decreased(P<0.05 or P<0.01).There were no significant differences of the NO levels and the expression levels of iNOS protein between LPS+XBJ group and LPS +PDTC group (P>0.05),but the expression level of NF-κB p65 protein in LPS+PDTC group was lower than that in LPS+XBJ group(P<0.05).Conclusion XBJ can inhibit the production of NO and the expression of iNOS protein in VEC;its mechanism may be related to inhibiting the activation of NF-κB to control inflammation.
