Abstract The aim of present study was to explore protective and curative effects of Malve neglecta on kidneys. In silco study with network pharmacology was performed to find out potential target organs, genes and cellular cell lines which confirmed kidneys as target organ of phyto-constituents present in Malva neglecta extract. Gentamicin (40 mg/kg, i.p) was given to induce renal toxicity. Prophylactic study was performed with 300-, 600- and 900 mg/kg doses to find out nephro-protective and -curative effects and curative potential was evaluated at 900 mg/kg dose. Renal function biomarkers, blood urea, BUN, serum creatinine and uric acid, and oxidative stress measuring biomarkers, SOD, CAT, GSH and MDA levels in kidney homogenate were quantified at the end of study. Treatment groups showed decrease in blood urea, BUN, serum creatinine and uric acid levels dose dependently and curative group also showed decline in these biomarkers. SOD, CAT, GSH levels were increased and MDA level decreased in treatment groups significantly as compared to toxic control which revealed the role of oxidative stress in renal damage and anti-oxidant power of MN. Data suggested that use of MN along with drugs causing renal toxicity may prove beneficial due to its nephro- protective and curative effects.

ABSTRACT In this paper, existence and uniqueness results are established for a nonlinear sequential Hadamard fractional differential equation with multi-point boundary conditions, via Banach and Krasnosel'skiĭ's fixed point theorems and Leray-Schauder nonlinear alternative. An example illustrating the existence of a unique solution is also constructed.

RESUMEN En este artículo se establecen resultados de existencia y unicidad para una ecuación diferencial fraccional nolineal secuencial de Hadamard con condiciones de borde multi-punto, a través de teoremas de punto jo de Banach y Krasnosel'skiĭ's y la alternativa nolineal de Leray-Schauder. Se construye un ejemplo ilustrando la existencia de una única solución.

Abstract Urolithiasis is a disorder of kidneys in which stones formation occur due to the excessive deposition of minerals in the urinary tract. It affects 12% of the population worldwide. Salvia hispanica seeds are rich source of quercetin which has preventive role in renal stone formation. The study objective was to explore scientifically the anti-urolithiatic effect of Salvia hispanica seed’s methanol extract using in vitro and in vivo urolithiasis models. For in-vitro study nucleation, growth and aggregation assays were performed. In vivo study was performed on rats and they were divided into six groups (n=6). Group-I was given vehicle only. Group-II was disease control, treated with 0.75% EG in drinking water which triggered urolithiasis. Groups-III received cystone (750 mg/kg, orally). Groups IV–VI were treated with extract at 100, 300 and 700 mg/kg doses orally once daily. Groups III-VI additionally received 0.75% EG in drinking water. In vitro study revealed concentration dependent increase in percentage inhibition of crystal’s nucleation, growth and aggregation. In vivo study revealed anti-urolithiatic activity by lowering oxalate, calcium, phosphate, sodium and potassium levels in the urine and the serum uric acid, blood urea nitrogen, total proteins and total albumin. Salvia hispanica seeds are good alterative of allopathic anti-urolithiatic drugs to treat urolithiasis.

Abstract The study aim was to evaluate the toxic potential of two polyherbal formulation i.e. “ PH 1 & PH 2” and scientific validation of their anti-asthmatic use. Acute oral toxicity study as per OECD 425 TG was conducted. For validation of anti-asthmatic claim, in vivo assay named Ovalbumin (OVA)-induced murine method in Wistar rats was used. Eosinophils and IgE antibody were quantified post-administration of low and high doses of the formulations. No mortality was observed in acute toxicity study. Elevated levels of alkaline phosphatase and damaged liver structure indicating the hepatotoxicity were more pronounced in PH 2 treated rats. Congestion in kidney tissue and increased urea level were evident of the nephrotoxic nature of PH 2 in animals. Treatment with selected polyherbal products decreased the MDA level while increasing the SOD and GSH levels in lung tissue homogenates. The maximum decrease in IgE load (3.18 ± 0.08 IU/mL) was found in rats treated with 12 mg/kg dose of PH 1 followed by 100 mg/kg dose of PH 2 (3.44 ± 0.06 IU/mL). It was concluded that both polyherbal formulations had anti-asthmatic activities, however, PH 1 exhibited the liver and kidney toxicity and should be cautiously used.

The present study was conducted to find out the ethambutol resistance pattern of indigenous isolates of Mycobacterium tuberculosis from Tuberculosis diagnosed human patients. A total of 172 specimens were collected from six different sources and comprised of 84.9% sputum, 10.5% pus and 4.7% bronchial washings. There were 70.9% males and 29.1% females with 84.30% pulmonary and 15.69% extra-pulmonary tuberculosis. The Mycobacterium tuberculosis isolates collected from primary culture were further studied to determine their pattern and level of resistance. The inoculums were prepared using 0.5 Mac Farland turbidity standards. Five different concentration of ethambutol were used in Lowenstein Jensen (LJ) medium i.e. 2μg/ml, 4μg/ml, 6μg/ml, 8μg/ml and 10μg/ml for sensitivity testing. Data showed 10 (5.8%) resistant and 162 (94.2%) sensitive Mycobacterium tuberculosis out of total 172 clinical isolates. The growth was not inhibited at 1st (2μg/ml) and 2nd (4μg/ml) drug levels, while growth of 50% isolates inhibited at 3rd level (6μg/ml), 30% inhibited at 4th level (8μg/ml) and 20% at 5th level (10μg/ml). The last three levels are above the therapeutic index and not recommended in actual clinical practice. It is thus conceivable to explore some other more effective chemotherapeutic agents, modify combinations or find more effective procedures to stop morbidity and mortality due to ethambutol resistant Mycobacterium tuberculosis.
