DOXORUBICIN INDUCED COGNITION IMPAIRMENT IN RAT MODEL

 Objective: Doxorubicin (DOX) is a chemotherapeutic agent commonly used to treat a variety of cancers despite having well documented adverse sideeffects in organs like heart, liver, and kidney. The damage caused to brain, if any, and to what extent is, however, still not clear and the present studywas undertaken to estimate the possible role of DOX inducing cognitive impairment in Wistar rats.Methods: The study carried out in two groups of Wistar rats (n=6) with one group receiving DOX, and the other only normal saline used as control.During and after the experimentation period cognitive level of each rat was measured using Barnes maze (BM) till 8 weeks. At the end of theobservation period (after 8th week), a series of biochemical and histopathological studies were carried out after sacrificing the animals.Results: Errors to reach target and time taken to reach the target was found in BM experiment, elevated levels of antioxidants and hemoglobin wasfound reduced significantly in the DOX treated group when compared to the controls while histopathology of brain cells of DOX treated group alsoshowed reduction in hippocampal cellularity and cell death in hippocampal area suggesting evidence of oxidative damage caused by DOX treatment.Conclusion: Parameters in this study which not only conclusively show the damage caused to brain by DOX, but also estimates the changes caused toeach indicator by this drug.Keywords: Chemotherapy, Brain, Hippocampus, Oxidative stress

An analytical study to evaluate the safety of reusing of the vomited leech in leech therapy: A pilot study

Background: Leech therapy is a point of attraction in the medical as well as in the scientific world due to its various outstanding properties, while studying the Ayurveda and scientific literature one can find difference, i.e., discarding after single use as per modern literature, but in Ayurveda, it can be reused after 7 days of leech therapy. Studies of such kind were not carried or published in any scientific journals, so ethical approval and developing scientific methods for validating the study were necessary, so a pilot study began with ethical clearance. Objective: The objective of the study was to evaluate the bacterial and fungal count of leech saliva and blood emesis before and after leech therapy using disc diffusion method. Materials and Methods: Leeches were collected from the normal habitat from Mangalore region possessing the same weight and morphological characteristics as that of the Nirvisha Jalouka as mentioned in classics (Shanku-mukhi). The selected leeches were stored in well water having nonchlorinated with minimum bacterial load. The well water was selected from three geographical regions of Belagavi city, and among them, one sample was selected having minimal bacterial load. Ten patients with infectious skin diseases who were indicated for Jalaukavacharana (Vidradhi, Dushta-vrana) were selected. The experimental leech saliva was tested for total bacterial count (TBC) and total fungal count (TFC) before and on 8th day of application, along with venous blood of the patient and blood vomitus of leech after application was tested for TBC and TFC. Statistical analysis was done based on TFC and TBC before and after application. Results: TBC and TFC of leech saliva at 8th day and before application were similar which indicates the leech gut has destroyed the bacteria or inhibited the growth of bacteria. Conclusion: TBC and TFC help to produce evidence that after application of leech and proper vomiting will not allow the growth of bacteria. Hence, safely, it can be reused after 7 days
