    INTRODUCTION: Portal Hypertension causes Gastrointestinal Bleeding. It is most frequently due to Gastro Esophageal varices (65-70%) and isolated Gastric varices (10-15%). Endoscopic therapy is the only treatment modality that is widely accepted for the prevention of variceal bleeding, control of acute variceal bleeding, and prevention of variceal rebleeding. Endoscopic Variceal therapy includes Variceal Sclerotherapy and Variceal Band Ligation. The technique involves injection of a sclerosant into (intravariceal) or adjacent to (paravariceal) a varix. Some paravariceal injection usually takes place during attempted intravariceal therapy. The sclerosants used include sodium tetradecyl sulfate, sodium morrhuate, ethanolamine oleate, and absolute alcohol. AIM OF THE STUDY: To study the Esophageal Motility changes following Endoscopic Variceal Band Ligation or Sclerotherapy using High resolution Manometry. MATERIAL AND METHODS: Study Design : Prospective study. Total no. of subjects : 20. Patients who were diagnosed to have portal hypertension who were referred to the department of Gastroenterology at Madras Medical College Hospital were included in this study. The diagnosis of portal hypertension and its etiology was established by Clinical Biochemical Imaging and Histology if needed An informed consent was obtained from these patients, A baseline Esophageal Manometry is done for these patients using High Resolution Manometry Depending on the clinical situations these patients were subjected to Endoscopic Variceal Sclerotherapy and or Variceal Band Ligation. CONCLUSION: Endosocpic Sclerotherapy and Endoscopic Variceal Band Ligation causes Dysmotility. Dysmotility can occur a late complication due to persistent chronic inflammatory changes. High Resolution Manometry is a Novel method to identify focal segmental changes in motility following Endoscopic Sclerotherapy and Endoscopic Variceal Band Ligation. In this study there was manometric changes in the form of decreased amplitude and velocity of contraction in the Lower Esophagus. The motility changes were more commonly found in the Endoscopic sclerotherapy group. Though in our study the two groups were not comparable in Number. The number of sessions did not correlate with the Endoscopic Sclerotherapy group but in a group of patient who underwent both therapy they developed motility changes after third session. In this study there were no abnormal waves and Non peristaltic waves, no prolongation of duration of peristaltic waves. None of these patients had any symptoms. Endoscopic variceal sclerotherapy causes Esophageal motility changes six months after therapy. There was no motility changes following Endoscopic Variceal Band Ligation alone was used. These changes do not causes any dysmotility symptoms in patients

    A Comparative Analysis of Age-Stage Two Sex Life Tables in Distinct Forms of Callosobruchus maculatus (F.): Insights into Population Dynamics and Reproductive Strategies

    Get PDF
    Callosobruchus maculatus, the bean weevil, is a fascinating insect that showcases remarkable adaptations for survival. Found in tropical and subtropical regions, it has become a global pest due to its adaptability and hitchhiking capabilities, causing substantial grain losses. This small beetle, part of the Chrysomelidae family, serves as a valuable model organism in entomology and agricultural research. One of the key aspects of Callosobruchus maculatus that captures the attention of scientists is its dichotomy between active and inactive forms. These two forms represent distinct survival strategies employed by the beetle to navigate its ever-changing environment. The present study provides a comprehensive overview of the study on Callosobruchus maculatus, highlighting the two distinct forms of the species, their adaptations, and the significance of understanding their lifetable parameters. It emphasizes the ecological, practical, and research-oriented implications of this study, ranging from ecological insights to pest management strategies and the optimization of mass multiplication protocols. These forms exhibited notable differences in various life history parameters and survival characteristics. Flightless-inactive females had longer preoviposition and oviposition period and laid a significantly higher average of eggs per female with higher reproduction potential. Female fecundity (eggs/female) was much lower in the flight-active form (18.6) than in the flightless-inactive form (84.10) and maintained constant survival rate. Life expectancy values were generally lower for the flightless-inactive form compared to the flight-active form across different stages and sexes. Both males and females in the flight-active form exhibited a consistent and relatively high life expectancy, with a 100% chance of survival throughout all age intervals. Overall, these findings provide a comprehensive understanding of the differences in life history traits, reproductive strategies, and survival patterns between the flight-active and flightless-inactive forms of Callosobruchus beetles in a controlled laboratory environment
