OBJECTIVE:To investigate the preventive effect of Gynostemma pentaphyllum water extract on model rats with stress-induced gastric ulcer. METHODS:60 rats were randomly divided into normal group,model group,positive group (Sanjiu weitai granules,3.69 g/kg)and G. pentaphyllum water extract high-dose,medium-dose,low-dose groups(4.0,2.0,1.0 g/kg,cal-culated by crude drug),10 in each group. All rats were intragastrically administrated,once a day,for one week. After 2 h of ad-ministration,except for normal group,rats were induced to stress gastric ulcer model by water immersion method in other groups. After 3 h of modeling,ulcer index (UI),ulcer inhibition rate were detected;superoxide dismutase (SOD) and malondialdehyde (MDA)in serum,tumor necrosis factor-α(TNF-α),prostaglandin E2(PGE2),nitric oxide(NO)and endothelin-1(ET-1)levels in gastric mucosal tissue were determined. RESULTS:Compared with normal group,SOD level in model group was decreased, while MDA level was increased in serum(P<0.05);PGE2,NO levels were decreased,TNF-α,ET-1 levels were increased in gas-tric mucosal tissue (P<0.05). Compared with model group,UI in administration groups were obviously decreased,above-men-tioned indexes were obviously improved,which showed certain dose-dependence. And the levels of PEG2,ET-1 of gastric mucosal tissue in G. pentaphyllum water extract high-dose group improved more obviously than positive group,with statistical significances (P<0.05). CONCLUSIONS:G. pentaphyllum water extract plays a role in preventing gastric ulcer by regulating serum SOD-MDA balance,gastric mucosal tissue NO-ET-1 balance and reduce the degree of gastric mucosa injury,etc.

OBJECTIVE:To study the antihypertensive effects of water decoction of Eupatorium lindleyanum on spontaneously hypertensive rats (SHR) and corresponding mechanism. METHODS:50 SHR were randomly divided into model group,captopril tablets group(positive drug,10 mg/g)and the groups of high,medium and low-dose(65.45,32.73,16.36 g/kg)water decoction of E. lindleyanum,with 10 rats in each group. The rats in the model group were given normal saline ig,while those in other groups were given corresponding drugs ig,once a day,for 7 consecutive weeks. The systolic blood pressure (SBP) and diastolic blood pressure(DBP)of the caudal arteries of the rats were measured every week,and the dynamic changes in the blood pressure of the rats as a result of drug intervention were recorded. The rats were sacrificed 7 weeks later,and the levels of endothelin(ET), angiotensin (AngⅡ) and nitric oxide (NO) in serum were determined. RESULTS:After 7 weeks of drug use,compared to the model group,the rats in the drug administration groups had significantly lower SBP and DBP of the caudal artery(P<0.05),show-ing obvious dose-effect and time-effect relationships in the antihypertensive effect of water decoction of E. lindleyanum,and had ob-viously lower levels of NO and AngⅡ and markedly higher level of ET in serum,demonstrating a dose-effect relationship. CON-CLUSIONS:The water decoction of E. lindleyanum has an obvious antihypertensive effect by a mechanism which may be related to decrease in the levels of NO and AngⅡin serum and increase in the level of ET therein.

Objective To investigate the MRI features of intracranial lymphoplasmacyte-rich meningioma and the corelation between the MRI features and pathologic findings. Methods The MRI and pathologic data of 7 patients with lymphoplasmacyte-rich meningioma were reviewed retrospectively. All cases were proved by surgery and pathological examinations. Results All lesions were solitary. The tumors crawled along meninges in 6 cases and in 5 cases the tumors did not appear as mass lesions. In 2 cases, the tumors appeared as half-moon. The boundary of all of the tumors was unclear, accompanying heavy peritumoral brain edema. The brain invasion can be seen in 7 cases. The lesions showed hypo-isointense signal on T1 WI in 7 cases, hyper-isointense signal in 5 cases and hypo-isointense in 2 cases on T2 WI.Enhancement scan demonstrated marked enhancement in 7 cases. Extensive thickening of the meninges was observed in 6 cases. Pathological results showed that the cells were abundant and diversified, with a great quantity of lymphoplasmacytes, and there were typical meningeal epithelial cells area in the surgical specimen. Conclusion The MRI findings of lymphoplasmacyte-rich meningioma show some features different from other common meningiomas, which would be helpful to the diagnosis and differential diagnosis.

The frequency of car accidents have contributed to increasing numbers and sevtrities of injuries to the supracondyle of the femur. the supracondylar fractures of the femur have always created complicated problems associated with restoration of the distal articular joint surface, avoidance of subsequent stiffness of the knee Joint, difflculties in management of the fracture. The author reviewed 31 supracondylar fractures of the femur in 31 patients who were treated in the department of Orthopedic Surgery, Kyungpook National University Hospital for the 6 and half years period from Jan., 1973 to Jun.,1979. The incidence of supracondylar fractures was more common in male than in female. Most of fractures occured in persons who are in their third and fourth decades. Ellciting cause were mainly traumatic and most of them were due to car accidents. The author has adopted the classification of supracondylar fracture of the femur by Neer. Of 31 cases of supracondylar fractures, there were 3 cases of Group 1 fracture, 10 cases of Group II-A fracture, 10 cases of Group II-B fracture, and 8 cases of Group III fracture. Sixteen cases were treated conservatively, 15 cases were treated by open reduction and internal flxation with various devices. The result was more satisfactory in cases by open treatment than In closed treatment.
