ABSTRACT

Phaeophyscia hispidula (Ach.) Moberg, foliose lichen is widespread in Garhwal Himalayas and grows luxuriantly on different substratum in polluted as well as non polluted sites, where no other macrolichens are able to colonize. The elemental concentration and biochemical parameters in P. hispidula collected from Dehra Dun city were analyzed to assess its tolerance to heavy metals. The major source of pollution in the city is automobiles. Among the biochemical parameters protein was significantly and negatively correlated with pigment concentrations (r= -0.3838 (Chl.b); -0.5809 (Carotenoid); -0.5034 (OD)) however it is significantly positively correlated with Cd (r = 0.6822: P<0.01). Among heavy metals, Cd was negatively correlated with Cu (r = -0.4639), Fe (r = -0.2676), and Zn (r = -0.0549). It was observed that the chlorophyll and protein content increased parallel to the level of metallic pollutants indicating the mechanism of stress tolerance in P. hispidula. The study shows that P. hispidula is tolerant to inorganic pollution and a useful tool for biomonitoring of air quality in the Himalayan region.

ABSTRACT

Cerebral malaria is the most common cause of non-traumatic encephalopathy in the world. The mainstay of therapy is either quinine or artemisinin, both of which are effective antimalarials. The clinical picture of cerebral malaria may persist or even become worse in spite of the clearance of parasites from blood. The death rate is unacceptably high even with effective antimalarials in tertiary care hospitals. The mortality increases in presence of multi organ failure (renal failure, jaundice, respiratory distress, severe anaemia, lactic acidosis, etc.). The pathogenesis of cerebral malaria is multifactorial and includes clogging, sequestration, rosette formation, release of cytokines, cerebral oedema, increased intracranial hypertension, etc. Attempts are made to use adjuvant therapy which will act through alternate mechanisms and address one or more of the pathogenetic processes. In this review, we have discussed the role of corticosteroids, pentoxifylline, desferrioxamine, mannitol and newer agents in the treatment of cerebral malaria. Though the literature on adjuvant therapy in cerebral malaria is large enough, there are a number of shortcomings in the clinical trials, many being open and non randomized or of very small sample size. Further research is of utmost importance through large multicentric, double-blind controlled trials to show the efficacy of any of these drugs.

ABSTRACT

In view of the controversies existing regarding the atherogenic potential of smoking, this study was conducted in 40 healthy young male Cigarette smokers and 40 age and weight matched male non smokers, to find out the difference in the serum lipid profiles of both the groups. Subjects in both the groups were in the age range of 25 and 35 years having no history of alcohol abuse or diseases like diabetes mellitus or obesity. The mean serum total cholesterol (177.3 +/- 32.5 mg/dL) and LDL cholesterol (100.2 +/- 31.0 mg/dL) were significantly higher in smokers (p < 0.05) whereas mean serum HDL- Cholesterol was (43.2 +/- 5.8 mg/dL) was significantly lower (P < 0.05). Mean triglyceride (170.8 +/- 59.7 mg/dL) was significantly higher in smokers than in nonsmokers (p < 0.01). In the fed state the total serum cholesterol level and triglyceride level was increased by 10.4 mg/dL and 51.1 mg/dL respectively in smokers whereas the increase was 4.8 mg/dL and 24.3 mg/dL respectively in nonsmokers. There was less rise of HDL cholesterol (1.9 mg/dL) in smokers as compared to that in nonsmokers (3.4 mg/dL) and in LDL-cholesterol (1.8 mg/dL) in smokers compared to nonsmokers (3.4 mg/dL) in fed state.

ABSTRACT

A simple; anatomic extraperitoneal approach for the repair of varying sizes of postoperative ventral abdominal herniae is described. This involves reconstruction of linea alba and repair using interrupted nylon sutures without tension on the edges. 27 patients managed with this technique between 1987 and 1990 with a follow up of one to four years; with neither death nor hernia recurrence are presented

ABSTRACT

Fifteen (34.8%) of 43 patients of falciparum malaria screened for urinary abnormalities showed significant proteinuria (greater than 150 mg/24 h), haematuria (greater than 1/HPF) and casts, with or without azotaemia. Light microscopic examination of renal biopsy tissue from 12 patients revealed mesangial and endothelial proliferative change in 8, and acute tubular necrosis in one patient. Immunofluorescence showed IgM alone, or IgG and IgM along with C3, in 7 patients within the mesangium or along the capillary walls. Repeat kidney biopsy after 6 wk in 5 patients revealed no residual pathology indicating the reversible nature of the lesions.
