Polymorphonuclear leukocyte functions in patients with acute rheumatic fever and rheumatic heart disease

Polymorphonuclear (PMN) cell function was assessed in 30 children with active rheumatic fever (ARF) (Group I), 30 cases with active rheumatic heart disease (RHD) (Group II), 28 cases of ARF and RHD in remission (Group III) and 34 adults with quiescent RHD along with their age matched controls. All the groups showed normal spontaneous and chemotactic movement. Phagocytosis of yeast particles was significantly reduced in groups II (P less than 0.0005), III (P less than 0.025) and IV (P less than 0.005). The opsonic activity of disease sera was low in all 4 groups (P less than 0.0005). The intracellular metabolic activity was moderately elevated in Group III. Phagocytosis and opsonic activity were thus persistently low in all the groups including the remission and quiescent group.     

Herpes zoster and post-herpetic neuralgia--a clinical trial of aspirin in chloroform for anodyne

Pain associated with Herpes Zoster (HZ) and Post-herpetic Neuralgia (PHN) has been a challenging task to manage with ease. Topical aspirin dissolved in chloroform is an effective means of reducing pain due to HZ and PHN in most patients. The locus of pain origin and analgesia induced by topical aspirin is supposed to be at cutaneous free nerve ending pain receptors. The present study was conduced in fifty two patients of HZ and PHN. Pain intensity before and after the application of drug was measured with help of Sort Form McGill Pain Questionnaire (SE-MPQ). Most of the patients experienced relief of pain within 1-5 minutes after the aspirin-chloroform application. Maximum relief was achieved in about 30-40 minutes and persisted for 5-6 hrs. In the beginning 3-4 applications were required but frequency decreased gradually as the pain abated.     

Cell-mediated immune response in mice treated with steroidal contraceptives.

The splenomegaly assay (Simonsen, 1962) was standardized using different strains of rats and mice. Male Wistar rat (donor)-female Swiss mouse (host) was found to be the suitable combination that could be employed in subsequent experiments to study the potential of contraceptive steroids to alter CMIR. The index of splenomegaly appeared to increase in case of mice treated with combination oral contraceptives (Ovulen, Ovral or Enovid). The differences observed, however, neared significance only in the case of Ovral (0-05 less than P less than 0-1). Neither chlormadinone acetate nor megestrol acetate significantly altered the index of splenomegaly.     

Growing problem of methicillin resistant staphylococci--Indian scenario

In the present study MRSA prevalence increased from 12% in 1992 to 80.83% in 1999. Indian literature shows that MRSA incidence was as low as 6.9% in 1988 and reached to 24% and 32.6% in Vellore and Lucknow in 1994 and was of the same order in Mumbai, Delhi and Bangalore in 1996 and in Rohtak and Mangalore in 1999. However, in some of the centres it was as high as 87%. All the MRSA isolates in India including in the present study were sensitive to vancomycin and resistance to netilmycin appears to be low among MRSA isolates in India. All the MRSA isolates were also found to be sensitive to teicoplanin in the present study. Like in other Indian studies, resistance to cotrimoxazole, erythromycin, gentamicin, other penicillins and cephalosporins appeared to be a common feature for MRSA isolates in the present study.     

Conceptual and methodologic challenges of assessing the short-term efficacy of Guggulu in obesity: data emergent from a naturalistic clinical trial

An open comparative trial was conducted in 58 adult obese patients (Body Mass Index > or = 25 kg/square metre). Group I (n = 27), non-drug, was advised diet (1200-1600 cals) and a brisk walk for 30 minutes. Group II, in addition, received Guggulu (Medohar) 1.5-3 gms/day for 30 days. Mean difference in weight loss between Guggulu and non-drug group was 0.32 kg (ns) on day 15 and 0.58 kg on day 30 (ns). The mean weight reduction in patients (> 90 kgs) was 1.92 kg (ns) and 2.25 kg (ns) higher in Guggulu group. All patients weighing > 90 kg lost weight in Guggulu group whilst 3 in non-drug group did not lose weight. Guggulu was tolerated well. The data from this pilot study suggest a synergistic diet-Guggulu interaction over 30 days in patients weighing > 90 kgs which needs to be confirmed in a large placebo controlled study.
