Item Clinical evaluation of chandonium iodide as a nondepolarising muscle relaxant.(1990-10-01) Kumar, D; Bhatia, V K; Yajnik, S; Gaur, S P; Nityanand, SThe effect of chandonium iodide (as a non-depolarising muscle relaxant) was studied in 50 patients of ASA grade I or II who were scheduled for surgery. The patients were divided into 2 groups according to the dose of chandonium iodide (0.2 and 0.25 mg/kg respectively). The onset and duration of action was found to be dose dependent. Intubation characteristics were good to fair in all the patients, the reaction to intubation being either absent or mild. There was mild and transient rise in pulse and blood pressure. No allergic reaction was observed in any patient and reversal characteristics were good in all the cases.Item Effect of anti-platelet therapy (aspirin + pentoxiphylline) on plasma lipids in patients of ischaemic stroke.(1993-04-01) Gaur, S P; Garg, R K; Kar, A M; Srimal, R CTwenty-one patients of ischaemic stroke were put on prolonged administration of antiplatelet drugs (aspirin 320 mg once daily with pentoxiphylline 400 mg thrice daily). The serum lipids along with other biochemical parameters were estimated before starting the treatment and after completion of 2 months of therapy. No significant changes were observed in any of the biochemical parameters including lipid profile except in serum high density lipoprotein (HDL) which increased significantly (< 0.05) after 2 months therapy. It is concluded that 2 months antiplatelet therapy has no adverse metabolic effect in patients of ischaemic stroke and the raised serum HDL may contribute to cerebral protective effect.Item Lipoprotein(a) and coronary heart disease in Indian population.(1999-12-28) Singh, S; Dwivedi, S; Melkani, G C; Rani, C; Gaur, S P; Mandal, S K; Mahua, JOBJECTIVE: Present study was undertaken to evaluate the role of lipoprotein(a) in coronary heart disease (CHD) patients and its relationship with other established risk factors. METHODS: Blood samples of 67 control patients (non-cardiovascular problems) and 222 CHD patients (> or = 4 weeks post myocardial infarction) were analyzed. Lipoprotein(a) was measured in serum samples by enzyme-linked immunosorbent assay utilizing rabbit polyclonal antibodies against purified human Lp(a). Step-wise linear discriminant analysis was used to find the important parameters to discriminate CHD and non-CHD subjects. RESULTS: The LDL to HDL cholesterol ratio (p < 0.01) and serum level of lipoprotein(a) (p < 0.01) were significantly higher in CHD patients. Levels of lipoprotein(a) were found to be higher in females compared to males (p < 0.01). Positive family history of CHD did not show significant difference in Lp(a) levels. Lp(a) level in CHD patients with positive family history of NIDDM and hypertension was higher than in with negative family history. CONCLUSION: Clinical significance of serum level of Lp(a) and albumin in determining the risk of CHD has been observed. Lp(a) alone could correctly discriminate a CHD individual from a control subjects by 95%. Estimating of Lp(a) together with albumin provided 99% correct discrimination between control and CHD patients. These results also suggest that Lp(a) together with malnutrition could be responsible for the increased incidence of CHD in Indians. It is also indicated that in females atherothrombogenic potential of lipoprotein(a) remains suppressed before menopause but after this stage women lose this advantage.Item A multicentric prescription event monitoring study of Verorab.(1996-04-01) Agarwal, H O; Gaur, S P; Ghosh, T K; Marfatia, S P; Rajavelu, S; Saxena, N B; Siddiqui, M N; Srivastava, D KItem Oxidative stress and metabolic control in non-insulin dependent diabetes mellitus.(1997-12-22) Singh, S; Melkani, G C; Rani, C; Gaur, S P; Agrawal, V; Agrawal, C GThe aim of this study was to evaluate conjugated dienes in subjects with non-insulin-dependent diabetes mellitus (NIDDM) and its metabolic control. To achieve good metabolic control in addition to dietary management oral hypoglycemic agents such as glibenclamide, gliclazide and metformin were given to patients. Human plasma low-density lipoproteins (LDL) were delipidised and triglycerides (LDL-TG) and cholesterol esters (LDL-CE) were separated. Conjugated dienes in LDL-TG and LDL-CE of subjects with NIDDM (n = 90) and normal glucose tolerance (NGT) (n = 30) were measured using second derivative of uv absorption spectrum. Hypoglycemic agents lowered substantially concentration of cis, trans (c, t) and trans, trans (t, t) conjugated dienes in LDL-CE and LDL-TG. The duration of NIDDM has shown significant correlation (p < 0.001) with conjugated dienes in LDL-TG. Concentration of c, t and t, t-conjugated dienes in LDL-CE and LDL-TG were found significantly higher in subjects with NIDDM than NGT (p < 0.001). In conclusion, NIDDM, status of metabolic control and duration of diabetes have strong positive relation with oxidative stress.Item Platelet functions & lipid profile within 24 hours following an attack of TIA, thrombotic & haemorrhagic stroke.(1994-06-01) Gaur, S P; Garg, R K; Agarwal, S; Kar, A M; Srimal, R CThe present study was undertaken to evaluate comparatively the lipid profile and platelet functions within 24 h of the three most frequent types of stroke encountered in clinical practice. Twenty patients of transient ischaemic attacks, 22 of thrombotic stroke and 26 of haemorrhagic stroke (hypertensive putaminal haemorrhage), all within 24 h of the acute event, and 21 control subjects were studied. Spontaneous platelet aggregation, platelet aggregation induced with adenosine diphosphate (2.5, 3.75 and 5.0 microM) and lipid profile (serum cholesterol, triglycerides, high density lipoprotein, low density lipoprotein and very low density lipoprotein) estimations were performed in all the subjects. Mean platelet aggregation values were significantly lower in haemorrhagic stroke patients as compared to controls. Serum cholesterol, triglycerides and very low density lipoprotein levels in ischaemic groups i.e., transient ischaemic attacks and thrombotic stroke patients, were significantly elevated, more so in the former group. It appears that platelet hypofunction has a role in the pathogenesis of hypertensive putaminal haemorrhage while in patients of transient ischaemic attack and thrombotic stroke, lipids may be a contributing factor in cerebral atherogenesis.Item Platelet functions and lipid profile in haemorrhagic and thrombotic stroke patients.(1994-04-01) Garg, R K; Gaur, S P; Kar, A M; Srimal, R CThe present study was conducted in 17 patients of haemorrhagic stroke (HS), 19 patients of thrombotic stroke (TS) and 14 control subjects. In each subject platelet functions (spontaneous platelet aggregation (SPA), aggregation induced with 10, 5, 2.5 microM ADP and 10 micrograms/ml of collagen) and complete lipid profile (total cholesterol, triglycerides, high density lipoprotein [HDL], low density lipoprotein [LDL], very low density lipoprotein [VLDL] and LDL/HDL ratio) were performed within 7 days of onset of stroke. Platelet aggregation with 2.5 microM ADP was significantly lower (P < 0.05), in both the stroke groups in comparison to controls. No other changes were significant. Mean serum triglycerides and VLDL of TS group were significantly higher than that of controls. Mean LDL/HDL ratio of the same group was significantly lower than HS group. It can be concluded that alterations in platelet functions and lipid profile are induced by both types of strokes in acute stage.
