Variability Study Analysis for Half-sib Families under Control Environmental Conditions in Neolamarckia cadamba (Kadamb)

Neolamarckia cadamba is a widespread medium-sized deciduous forest tree over most of India, Bangladesh, and Sri Lanka. Twenty-half-sib progenies of kadamb (Neolamarckia cadamba) from various regions in Bihar, Rajasthan, and Uttar Pradesh were sown in a glasshouse in 2022 in order to assess the genetic diversity using non-hierarchical Euclidean cluster analysis. Significant variation was seen in the biomass and morphological traits of a few plus trees. Under greenhouse conditions, significant differences were seen in the growth parameters of plus tree progenies. Six clusters were formed from the twenty NPTs, according to the genetic divergence analysis. Clusters V and VI were found to have the greatest inter-cluster distance (5.530). The cluster (4.258) displayed the highest intra-cluster distance. As a result, there was a genetic divergence between clusters. Therefore, in order to obtain high-yielding genotypes in Neolamarckia cadamba, hybridization involving trees of clusters VI and V is advised. Collar diameter was a major factor in the creation of genetic diversity and contributed the most to the overall divergence. The superior plus trees of cluster V (NPT4, NPT5, NPT11, NPT12, NPT13, NPT17) and cluster VI (NPT18, NPT19, NPT20) may be taken into consideration as possible parents for a future tree improvement program in Neolamarckia cadamba due to their high cluster mean and large genetic distance.

An Analytical Study Of Histopathological Findings Of 100 Cases Of Fistula-in-ano

Fistula-in-ano is one of the most difficult diseases confronted in ano-rectal patients in Shalyatantra OPD. Sushruta described Bhagandara along with its etiology, clinical presentation and treatment. The description of different types of Bhagandara (fistula-in-ano) are at par with the aetiopathogenesis of Fistula-in-ano of modern medical science. It is a very complicated condition arising out of various causes like pyogenic, tubercular, lymphogranuloma inguinale, inflammatory bowel diseases like Crohn's disease, ulcerative colitis etc. Identification of the aetiopathological factor is necessary for the success of treatment of fistula-in-ano. Histopathological study of tissue from tract of fistula-in-ano is an useful diagnostic tool for assessing the underlying pathology. In this study we use the benefits of histopathological examination from the primary site of the disease to detect the basic etiology. 100 cases diagnosed as fistula-in-ano attending Shalya OPD, Government Ayurvedic College Hospital were randomly selected for a period of one year i.e 2016-2017. After necessary investigations, tissue is collected from the primary site of fistulous tract during primary threading for Kshar Sutra therapy, in OT under local anaesthesia and sent for histopathological examination. The results of the above study were tabulated and lots of cases other than pyogenic cause were detected. The data were analysed with standard statistical methods. Without histopathological examination it is not possible to detect the underlying cause of fistula-in-ano.
