ABSTRACT
Background: Leprosy is an old, dreaded infectious disease caused by the obligate intracellular bacterium mycobacterium leprae. Leprosy still continues to be a significant public health problem in few countries including India. Oxidative stress caused by derangement in the balance between ROS and natural antioxidants plays a crucial role in the pathogenesis of leprosy. Hence this study attempts to assess the oxidative stress and antioxidant status in terms of Nitric oxide and uric acid.Methods: A case control observational study was carried out in100 untreated leprosy patients and compared with 50 healthy controls. Leprosy patients were divided as paucibacillary and multibacillary. Serum Nitric oxide and uric acid levels were estimated in both groups to find out correlation of Nitric Oxide with uric acid.Results: There was a significant rise in serum NO in both PB and MB leprosy as compared to controls. The uric acid level was significantly decreased in both PB and MB leprosy patients as compared to controls.Conclusions: Elevated NO levels indicate oxidative stress in leprosy patients, denoting its crucial involvement in the pathogenesis and nerve damage in leprosy. Low uric acid indicates decrease defence of antioxidants in leprosy.
ABSTRACT
Adverse drug reaction (ADR) is defined as “any response to drug which is noxious or unintended and occurs at a dose normally used in man for prophylaxis, diagnosis or treatment of diseases or for modification of physiological function”. Among the ADRs reported, cutaneous drug reactions are most common. Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE), also known as baboon syndrome (BS), is included in the spectrum of systemically induced allergic contact dermatitis. Characteristics of SDRIFE include a sharply defined symmetric erythema in the gluteal area and in the flexural or intertriginous folds without any systemic symptoms or signs. We present a case of 30-year-old female with baboon syndrome after taking the combination of paracetamol and diclofenac. Awareness of SDRIFE (BS) as an unusual drug reaction is especially important since the connection between skin eruption and drug exposure may easily be overlooked or misdiagnosed.
ABSTRACT
Malonyldialdehyde was measured in erythrocytes, aorta and spleen on feeding mice with high cholesterol diet in presence and absence of fish oil. Mice were grouped as: Group I: Control laboratory diet Group II: 0.16% cholesterol (sunflower oil) Group III: 1.16% cholesterol (sunflower oil) Group IV: 1.16% cholesterol (fish oil) After 7 weeks on their respective diets, erythrocytic, and splenic MDA levels were significantly higher in group III compared to controls. Also, MDA levels in aorta and spleen showed a significant increase in group IV males compared to group III males. However in group IV the erythrocyte MDA levels were almost equal to that in controls. This suggests that high cholesterol diet increases lipid peroxidation in erythrocytes, spleen and aorta. Addition of fish oil in the diet further increases lipid peroxidation in aorta and spleen, but not in the erythrocytes.
