ABSTRACT

A study of prevalence of tuberculosis in Kishtwar tehsil of Jammu region was conducted from June 1991 to May 1992. A total of one thousand two hundred ninety-eight rural as well as urban population suffering from various types of lung diseases was studied for prevalence of tuberculosis and a sizeable number (98) of patients were found to be positive of various types of tuberculosis, viz, pulmonary tuberculosis, tuberculous pleural effusion and miliary tuberculosis. Of the population studied 7.55% were found to be positive for tuberculosis and among them 88.76% patients were anaemic and the commonest type of anaemia was normocytic normochromic and normocytic hypochromic. The ESR was raised in almost of all the patients. Of the population, 80.61% were seen to be positive on skiagram chest and 58.16% were found to be positive on other diagnostic tests like Mantoux's tests, sputum for acid-fast bacilli, etc. Mantoux's test was positive in 27.55% cases and sputum was positive in 30.61% cases. All the cases studied were subjected to special investigations. The changes in parameters are consistent with the diagnosis of tuberculosis. Large family size, poverty, excessive smoking, illiteracy, etc, are the major contributing factors.

ABSTRACT

The effects of diazepam, propranolol or alcohol alone or in combination with each other were examined in ten normal healthy volunteers on tests of psychomotor function. Results showed impaired psychomotor performance persisting upto 4-5 h when the aforementioned agents given singly were tested on simple reaction time (SRT), multiple choice reaction time (MCRT) and critical flicker fusion frequency (CFFF) tasks. Digit cancellation task (DCT) was similarly affected by diazepam and alcohol only. No summation of adverse effects on psychomotor performance was noted when a combination of diazepam and alcohol, diazepam-propranol or alcohol plus propranolol were tested on SRT and MCRT. An additive impairment of CFFF was observed with alcohol - propranolol combination only. No summation of pharmacodynamic effects on DCT were noted when different combinations were used.

ABSTRACT

A study of work-related injuries at a hydro-electric project site (May 1991-April 1992) was undertaken to determine the incidence and pattern of the injuries out of a total number of 119 injuries in the year. A significant proportion of these were orthopaedic in nature and the commonest site of injury was limbs (both upper and lower limbs) like auto-amputations and head injuries. A large proportion of these accidents (24.37%) resulted in permanent disability likely to interfere in the normal activities or locomotion of those injured.

ABSTRACT

In a single dose crossover study, the effect of macrocomponents of food on the pharmacokinetics of a long acting preparation of anhydrous theophylline was investigated. Compared to fasting subjects, carbohydrate and fat rich diet caused an enhancement of absorption half life and a lower Cmax with a delayed tmax and elimination of the bronchodilator. Protein coadministration decreased AUCO-OC of the drug without significantly altering its absorption or elimination kinetics.

ABSTRACT

The effect of Aspirin, paracetamol and analgin on the kinetic profile of a single oral dose of chloroquine was studied in 8 healthy subjects. Aspirin did not alter the kinetic parameters of chloroquine whereas paracetamol and analgin significantly enhanced the Cmax and AUC0-alpha of chloroquine (P < 0.01, < 0.05 respectively).

ABSTRACT

Pharmacokinetics of a sustained release (SR) and conventional formulations of theophylline plus hydroxyethyltheophylline was compared with tablet aminophylline. Time concentration curve of serum theophylline with the three formulations after single and multiple dosage schedules revealed significantly retarded absorption with the SR preparation. SR tablet was also seen to produce uniform steady state levels with fluctuation of serum concentrations within the therapeutic range for a duration of over 12 hours. In comparison, aminophylline and conventional theophylline hydroxyethyltheophylline tablets produced sharp swings in steady state levels with trough levels dipping to subtherapeutic concentrations within 4-6 hours. SR formulation, therefore, is likely provide consistent serum levels and better therapeutic control in comparison to the other two conventional tablets.

ABSTRACT

The pharmacokinetics and bioavailability of valproic acid was compared in six healthy volunteers after single dose oral administration of 400 mg of the drug in tablet, capsule and syrup form in a crossover manner. Blood samples were collected for 48 hours and valproic acid concentration analysed by enzymatic immunoassay. Following the administration of the three dosage forms, the absorption varied (Ka = Syrup K 2.64 +/- 0.5; tablet 1.57 +/- 0.22; and capsule 0.55 +/- 0.55 h-1). Valproic acid concentration reached a peak level of 102.3 micrograms.ml at 1.9 h after syrup administration, 73 micrograms/ml at 3.3 h after tablet and 44.8 micrograms/ml at 5.4 h after capsule. The bioavailability of tablet and syrup formulation was not significantly different from each other but it differed from capsule form in that the bioavailability was only 52%.

ABSTRACT

Several agents with specific action on biologically active substances in brain were investigated for their influence on morphine analgesia. It was observed that imipramine, chlorpheniramine, and haloperidol antagonized morphine analgesia. The probable mechanism of action has been discussed.
