Myocardial infarction; streptokinase study on ST-segment resolution in patients age less than 40 years

Thrombolytic therapy for Acute Myocardial Infarction has been one of the most potent treatment ever developed for condition that kill more patients worldwide than any other. To evaluate the benefit and efficacy or observational studies of streptokinase therapy on ST-segment elevation resolution in different types of myocardial infarction that focus especially on the younger age group less than forty years. To observe the streptokinase therapy, in ST-segment elevation resolution, in age less than 40 years and in different types of myocardial infarction. The study was conducted at national institute of cardiovascular diseases [NICVD] of Pakistan, Karachi. Subject and All patients fulfilling the inclusion criteria for thrombolytic therapy were included. Baseline ECG recorded before streptokinase infusion and repeated at completion of infusion i.e. 90 minutes, day 1 and day 2. Streptokinase therapy on blood pressure, CKMB, and ST-segment resolution at 90 minutes, day 1, and Day2 in less than 40-year of age patient. The mean systolic blood pressure was 124+3.32 and 112+3.00 pre and post SK therapy reflecting a percentage decrease of 6.67 and highly significant [P<0.001]. The Diastolic blood pressure was decrease to 6.25% with a mean value of 76.80+2.70 and 72+1.91 before and after the Streptokinase therapy's, segment resolution at 90 minutes was decreased to 52.01 percent from the baseline and continued to decrease at Day-1 and Day-2 with a percentage reduction of 70.65 and 83.69% respectively. The P values were highly significant [P<0.001]. Thrombolysis improves survival when given within 12 hours of the onset of symptoms. The magnitude of benefit is greatest when reperfusion is established early. Age itself should not be considered a contraindication for fibronolysis

Comparative study of verapamil and thioridazine in acute opioid abstinence syndrome

To determine the effectiveness of verapamil and thioridazine in the treatment of acute opioid withdrawal syndrome in patients with chronic dependence on opioids. The study was conducted at Psychological Medicine Ward, Civil Hospital Karachi and Arshi Hospital, Naseerabad, F.B. area Karachi. A total of forty [40] patients were admitted for ten [10] days in hospital. No treatment was given during the first two days of admission after abrupt termination of opioid to observe the acute opioid withdrawal signs and symptoms. Patients were divided into 2 groups. Each group comprising of 20 opiate addicts. One group was given verapamil orally in a 40mg dose thrice daily and the other group was given thioridazine orally in a 10mg dose thrice daily from day 3 to day 9 of admission. The intensity of sign and symptoms were recorded by using subjective and objective opiate withdrawal questionnaire. Urine analysis for opioids was done on day 1, 5 and 10 of admission. Verapamil in comparison to thioridazine significantly decreased admission. Urine analyses for opioids were positive on day 01 while zero on day 10. Verapamil in comparison to Thioridazine was found to be safe and effective for the treatment of signs and symptoms of acute opioid withdrawal in in-door patients without any significant side effect

Toxicity of aminoglycoside [streptomycin] in the management of tuberculosis in placebo controlled study

The study was planned with an aim to identify the toxicity of streptomycin in the treatment of Tuberculosis. It's early an easy detection, establishment of existing damage without the use of sophisticated, costly and time consuming methods and also to assess the existing popular modalities of treatment. This prospective study was carried out in the Chest Ward and OPD JPMC Karachi and duration of twelve weeks. Patients were selected from chest ward and OPD of JPMC. Prospective randomized study of adverse effects of Streptomycin in the treatment of tuberculosis was done. It showed that like other antituberculous drug the streptomycin must be careful to use in combination therapy in the treatment of tuberculosis. The major side effects were those giving rise to serious health hazards, and required discontinuation of the drug. Minor side effects caused relatively little discomfort and often responded to symptomatic or simple treatment but occasionally persisted for the entire duration of drug treatment. In fact tuberculosis drugs are relatively toxic and side effects are not uncommon but most of them do not warrant drug withdrawal

Role of verapamil in acute opioid abstinence syndrome

To determine the effectiveness of calcium channel blocker, verapamil in the treatment of acute opioid withdrawal syndrome in patients with chronic dependence on opioid. A clinical study. The study was conducted at Psychological Medicine ward, Civil Hospital Karachi from January 1998 to April 1998. A total of twenty [20] patients were admitted for ten [10] days in hospital. No treatment was given during the first two days of admission after abrupt termination of opioid to observe the acute opioid withdrawal signs and symptoms. Then the verapamil was given orally to each patient in a 40mg dose thrice daily from day 3 to day 10 of admission. The intensity of signs and symptoms was recorded by using subjective and objective opiate withdrawal questionnaire. Urine analysis for opioids was done on day 1, 5 and 10 of admission. Verapamil significantly decreased the intensity of signs and symptoms of acute opioid withdrawal from day 4 to day 10 of admission. Urine analyses for opioids were positive on day 1 while zero on day 10. Verapamil was found to be safe and effective for the treatment of signs and symptoms of acute opioid withdrawal in in-door patients without any significant side effect

Effects of verapamil on ovalbumin induced contraction of sensitized guinea pigs lung parenchymal tissues, in vitro

Calcium ions play an important patho-physiological role in allergic reactions. The release of mediators from mast cells, synthesis of some newly formed chemical mediators; airway smooth muscle contraction and nerve impulse conduction are all dependent on the availability and influx of Ca++ ions. It is therefore likely, that Ca++ antagonist, verapamil may modify the allergic broncho-pulmunary responses. Investigate the effects of verapamil on ovalbumin induced contractile responses on lung parenchymal tissue strip in vitro. Guinea pigs treated with two high doses of ovalbumin i.e. 5 mg on day 0 and 10mg on day 2, intra-peritoneal. Twenty-one days after sensitization the effect of verapamil on guinea pigs, parenchymal tissue was evaluated by incubation of strip with verapamil for 10 minutes and treated with EC50 ovalbumin. Verapamil exhibits dose dependent inhibition of ovalbumin-induced contraction with significant effect at concentration 10-9 g/ml. On the basis of these observations two possible mechanisms for this protective effects were suggested, firstly verapamil may have suppressed mediator release and second verapamil may have inhibited the contractile effect of mediators on parenchymal smooth muscle. It is therefore suggested that verapamil may prove useful in the management of airway hyper-reactivity

Effects of Azelastine and Sodium cromoglycate in the inhibition of Broncho - Constriction of ovalbumin sensitized Lung Parenchymal Tissues of Guinea Pigs in Vitro

To see the ability of Azelastine and Sodium cromoglycate in influencing antigen induced contractile responses in isolated parenchymal tissues of Guinea pig in vitro. An experimental study. Department of Pharmacology and Therapeutics of Basic Medical Sciences Institute, Jinnah Postgraduate Medical Center [JPMC], Karachi during 1998. The Guinea pigs [n=10] were sensitized with ovalbumin and their parenchymal strips were exposed to different concentrations of ovalbumin to observe the EC50. Each sensitized parenchymal strip was treated with either Azelastine or Sodium cromoglycte in an organ bath for 10 minutes and treated with EC50 ovalbumin and contraction was recorded by Grass Polygraph model 7B. EC50 [n=6] of parenchymal strips [0.3x10-6 + 0.16x10-6g/ml] produced a mean response of contraction 9+0.44mm. Azelastine in concentration of 10-9 g/ml did not show any inhibitory effect but as the concentration increased to 10-8 g/ml, marked inhibition was recorded and with further increase in concentration by 10-7 g/ml, it completely antagonized the EC50 induced contraction. Sodium cromoglycate did not show any inhibition at concentration 10-8 g/ml while at higher concentration of 10-6 g/ml, it showed complete antagonism. Ovalbumin induced contraction of sensitized lung parenchymal tissues of Guinea pig in vitro is dose dependent and controlled better with Azelastine than Sodium cromoglycate
