Toxicity Induced by Low-dose of Total Alkaloids of Peganum harmala L. in female albino rats.
Peganum harmala L. is an essential medicinal plant. Its seeds contain the β-carbolines and quinazoline derivatives alkaloids as major bioactive compounds. The seeds have been used in traditional medicine as an emmenagogue and an abortifacient. It has numerous pharmacological consequences which includes antifungal, antibacterial, hypothermic, anticancer, antinociceptive, and reversible monoamine oxidase inhibition. The aim of this study is to evaluate the hormonal unbalance, ovarian toxicity, and oogenesis disruption caused by low-dose exposure to total extract of the alkaloids in the seeds of Peganum harmala L. After three months of daily IP administration of 3.99 mg/kg (≈1/40 DL50) of the extract. The manuscript results show a significant increase in the relative weight of the kidney, heart, lungs, brain, and ovaries. A significant increase in PAL by 196.7% and a significant decrease in ALAT, ASAT by 75.28% and 75.88% respectively, total and indirect bilirubin and serum urea by 67.53%, 48.78%, and 69.23% respectively. The hormonal analysis shows that FSH and estrogen have increased significantly by 116% and 300%. Histological study of the liver, kidney, and ovaries show sinusoidal inflammation and lymph-plasmocytes inflammation around the Centro-lobular vein, congestive follicles surrounded by endothelial cells, and the presence of a significant number and a huge size of secondary follicles and corpora luteal respectively. We suggest that the total extract of the alkaloids in the seeds at the dose used could stimulate folliculogenesis and ovulation by increasing gonadotropin hormones FSH and estradiol secretion.
STUDIES ON EFFECT OF ORGANIC MANURES AND BIOFERTILIZERS ON QUALITY PARAMETERS OF TURMERIC (Curcuma longa L.) VARIETIES
The present investigation on “Studies on the effect of organic manures, biofertilizers on growth, yield and quality of Turmeric (Curcuma longa L.) varieties” was conducted at College of Horticulture, Rajendranagar, SKLTSHU, Mulugu during 2019-20. The experiment was laid out in Factorial Randomized Block Design (FRBD) with 2 replications and 18 treatments. The results revealed that among all the organic manures, biofertilizers, varieties and their combinations, treatment M1 – FYM 45 t/ha + AMC (Arka microbial consortium) 1 lit per quintal manure recorded maximum antioxidant activity (12.01 µg mL-1), Curcumin content (5.75 %) and oleoresin content (9.25 %) followed by M3 – Vermicompost 14 t ha-1 + AMC (Arka microbial consortium) 1 l q-1 compost (12.53 µg mL-1), (5.46 %) and (8.22 %) respectively. Among the varieties, Salem recorded significantly the highest values for antioxidant activity (10.68 µg mL-1), curcumin content (6.03 %) and oleoresin content (10.20 %) followed by followed by V2 – First best treatment of first experiment (Vertical split of mother rhizome) of Rajendra Sonia variety (12.62 µg mL-1), (4.72 %) and (7.48 %) respectively. Among the interaction effects between organic manures, biofertilizers and varieties, the treatment M1V1 – FYM 45 t/ha + AMC (Arka microbial consortium) 1 lit per quintal manure + vertical split of mother rhizome of Salem variety recorded maximum antioxidant activity (10.18 µg mL-1) Curcumin content (7.14 %) and oleoresin content (12.38 %) followed by M3V1 – Vermicompost 14 t ha-1 + AMC (Arka microbial consortium) 1 l q-1 manure + First best variety of first experiment (Vertical split of mother rhizome) of Salem variety (10.51 µg mL-1), (6.41 %) and (10.69 %) respectively.
Response of fodder cowpea (Vigna unguiculata) to domestic sewage water irrigation
Though farmers` feed various vegetative biomass such as fresh, dry or preserved form for feeding livestock, the productivity was found low compared to the world average. As, fodder crops are found as a negligible crop, due importance is not given for cultivation of fodder crops in the field. Along, with this water is also found to be an important factor for not cultivating fodder crops. Fodder cowpea is one of the important fodder crops and fodder cowpea is deprived of resources mostly during cultivation due to its shorter duration and nitrogen fixing ability. As domestic sewage water contains nutrients required for plant growth and development, the experiment was an attempt to understand the response of fodder cowpea to realise its productivity and its effect on soil fertility. A pot experiment with fodder cowpea was laid out in complete randomized block design during rabi season, 2019 and 2020 to assess the effect of different sources of irrigation water on the growth, productivity, nutrient uptake of fodder cowpea and soil fertility after harvest of fodder cowpea. The irrigation treatments consist of application of ground water, domestic sewage water, ground water and domestic sewage water alternatively. Investigation resulted in higher growth, productivity and nutrient uptake of fodder cowpea and improvement in post-harvest soil available nutrients with application of domestic sewage water.
Monitoring of Winter Rice and Acreage Estimation Using Sentinel-1 SAR Data in the Ribhoi District of Meghalaya
Assessing the acreage for crop classification using optical satellite data encounters difficulties in India's rainy season because of continuous cloud cover. Microwave SAR data offers a potential alternative solution, and this research employed an efficient blend of multi-date Sentinel-1 SAR data. During the winter rice season of 2022-23, six sets of SAR data from different dates between June and August were examined in the Ribhoi district of Meghalaya. VH polarization was chosen for classification due to its greater consistency and reliability compared to VV polarization. Supervised machine learning classification algorithms, particularly support vector machine, were implemented for classification using ArcGIS software. The accuracy of this technique was assessed by comparing it with ground truth data, yielding an overall accuracy of 87% with a kappa coefficient of 0.73. Additionally, the estimated winter rice area from SAR images closely matched the reported area (9327 ha) from the State Department of Agriculture under rice cultivation in Ri-bhoi district, confirming result consistency.
Combined hepatocellular cholangiocellular carcinoma in ducks in India
Combined hepatocellular cholangiocellular carcinomas are the rarest form of primary hepatic tumors in avian species. Many reports of cHCC-CCA have been reported in animals with minimum reports in avian family. The present article deals with the occurrence of cHCC-CCA in ducks reported to Veterinary pathology department, LUVAS. Grossly the ducks were emaciated with presence of blood in the abdominal cavity, pale enlarged liver with yellow to green raised firm nodules of varying sizes. Histopathological examination confirmed mixed hepatic tumor as both hepatocellular and cholangiocellular carcinoma lesions were evident. Increased proliferation of the bile duct along with fatty change in hepatocytes with altered cytoplasm-nuclei ratio, anisokaryosis, anisocytosis, binucleation and presence of mitotic figures. Special staining revealed presence of thick fibrous capsule separating the tumor masses. To our knowledge this is the first case of occurrence of combined hepatocellular cholangiocellular carcinoma eluciadted in ducks in India.
