Abstract
The presence of one or more pesticides in a variety of mediums is responsible for their indirect toxicological events leading to cell senescence. In the present investigation, the endeavor was made to see the effect of pesticides Car- Benda-Zim (CBZ) and IMIdacloprid (IMI) alone and in combination with bone marrow-derived Mesenchymal Stem Cells (bMSCs) of buffalo origin. Isolated and cultured bMSCs were exposed to CBZ and IMI alone and in combinations at lower doses. Cells were observed for alterations in cell morphology, oxidative stress, mitochondrial damage and cellular senescence. bMSCs characterized for stem cell surface markers and found to be positive for AP, CD73 and OCT4. bMSCs exposed to IC25, IC12.5 and IC6.25 CBZ and IMI alone and combinations of IC12.5 and IC6.25 of CBZ and IMI. Results revealed significant reduction (p?0.05) in cell viability noticed on microscopic examination along with loss of normal cell morphology and increased in Reactive Oxygen Species (ROS) positive cells, cells with loss of ??m and number of senescent cells in CBZ and IMI treated groups. Lower dose combination groups showed elevated effects when compared with higher dose alone treated groups and control groups. Present findings suggest that CBZ and IMI induced cytotoxicity in bMSCs mediated via ROS production, altered ??m leading to the cell damage and predisposing senescence process. Moreover, the co-existence of CBZ and IMI in a medium has a considerably more toxic effect than their individual effect.

Abstract
BACKGROUND The study was aimed at encapsulating the evidence of in vitro and in vivo antiviral activities of molnupiravir and its active form against highly pathogenic SARS-CoV-2, the pathogen responsible for COVID-19, and finding out the efficacy and safety of molnupiravir in clinical trials. MAIN BODY Information on publications was explored on several databases, gray literature was reviewed, and the outcomes were discussed narratively. Molnupiravir's antiviral efficacy and associated mechanism of action have been verified in vitro against both non-COVID and multiple coronaviruses. Molnupiravir has been tried in preclinical investigations in numerous animal models against non-coronaviruses. Clinical studies in several countries are now being conducted to evaluate its antiviral efficacy in persons infected with COVID-19. The medication displays antiviral effect via generation of copying mistakes during viral RNA replication. CONCLUSIONS Molnupiravir is the first oral antiviral medicine to show considerable and convincing antiviral activity in vitro and in animal models. Molnupiravir stops the spread of SARS-CoV-2 in animals that have been infected and in cells grown in a lab. In a clinical research, early molnupiravir treatment reduced hospitalization and death risk in unvaccinated individuals with COVID-19. In the battle against SARS-CoV-2, it could be a potent weapon. However, its role in COVID-19 in moderate to severe cases is still up in the air, and more research is needed.

Abstract
Background Myrica esculenta (Family: Myricaceae) commonly known as Kaiphala or Katphala is a widely used medicinal plant in Ayurveda. In spite of its numerous medicinal attributes, no published work is available till date on pharmacognostical characterization and HPTLC analysis of its leaves. Objectives To investigate the pharmacognostical, physicochemical, and HPTLC profiles of M. esculenta leaves. Materials and methods The measures taken for pharmacognostical characterization were organoleptic study, macroscopy, microscopy, powder microscopy, leaf constant, fluorescence analysis, preliminary phytochemical screening and HPTLC spectra profile. Results Organoleptic and macroscopic studies found that leaves are lancoelate, thin, spirally arranged, dark green in color, with an astringent taste and acute apex. In transverse section, cuticularised epidermis having polygonal cells were found. Mesophyll cells were differentiated into single layered palisade cells on each surface and 2–3 layered spongy parenchyma, unicellular and uniseriate hollow trichomes, anomocytic stomata and bowl shaped vascular bundle in mid rib portion containing xylem and phloem tissues. Alkaloids, carbohydrates, flavonoids, glycosides, phenolic compounds and tannins were found present. Analysis on the leaf constants, powder microscopy, fluorescence characteristics and physical parameters resulted a valuable data to establish standards for the plant. HPTLC profile provides number of constituents present in the extracts with their respective Retention Factor (Rf). Conclusion Present report on pharmacognostical characterization and HPTLC analysis of M. esculenta leaves provides a vital diagnostic tool for identification, authentication and development of quality parameters of the species. Data obtained by present study may be considered as standard for future studies.

Abstract
Transplantation of isolated germ cells from a fertile donor male into the seminiferous tubules of infertile recipients can result in donor germ cells-derived sperm production. This technique has the potential to be used as an alternative strategy for producing transgenic livestock with higher efficiency and less time and capital requirement than the current methods. The objective of the present study was to investigate whether the homologous transplantation of isolated buffalo germ cells could result in colonization of recipient testes. Germ cells were isolated from prepubertal buffalo testes (4–6 months of age) by using double enzymatic digestion method and filtration through 80- and 60-µm nylon mesh filters. Further enrichment was achieved by differential plating on Datura stramonium agglutinin lectin-coated dishes and after that Percoll density gradient centrifugation as descrived by van Pelt et al. (1996) with minor modifications. A discontinuous density gradient was prepared with 60, 50, 40, 36, 34, 32, 30, 28, and 20% Percoll in a 15-mL centrifuge tube. The enriched germ cells were then labelled with red fluorescent linker dye PKH26 (Sigma, St. Louis, MO, USA) as per the manufacturer’s instructions, and ~10 million cells/testis were transferred into the rete testis of 3 recipients (16–18 months of age) under ultrasonographic guidance. After 45 days, testes were surgically removed and samples were prepared for analysis of labelled cells via wet mount of seminiferous tubules and individual cells isolation. When wet mount specimen were observed under a fluorescence microscope, PKH26-positive cells were identified on the seminiferous tubule basement membrane in all 3 recipients, which indicated that these cells had successfully migrated from the tubule lumen and were likely to be donor germ cells. In freshly isolated cells, clumps of PKH26-positive cells were observed, which indicated either cell division or extensive local colonization of specific areas of the seminiferous tubules. In conclusion, we report successful homologous transplantation of germ cells in prepubertal buffalo testes. Further studies will investigate functionality of transferred testicular cells.

Abstract
Diabetes is a growing disease worldwide and has emerged as a major healthcare problem in India. Insulin is an essential medicine for the treatment of diabetes. Large dairy animals, such as buffaloes and cows, may be used as bioreactors for cost-effective production of human insulin. The present study was aimed to produce transgenic buffalo embryos containing the human insulin gene through hand-guided cloning for production of transgenic animals. Buffalo female fetal fibroblast cells at passage number 3 were transfected using mammary gland- specific expression vector containing the human insulin gene under buffalo β-lactoglobulin promoter by nucleofection method and cultured with G418 drug for 3 weeks to obtain positive transgenic cell clones. Transgene integration into buffalo female fetal fibroblast genome was confirmed by PCR and Southern blotting. Nontransfected and transgene integrated cells were used as nuclear donors to produce embryos by the hand-guided cloning technique. The developmental competence and quality of embryos as judged by total cell number and TUNEL assay were compared among transgenic and nontransgenic (control) embryos. The blastocyst rate was lower (P < 0.05) for transgenic embryos than that of nontransgenic cloned embryos (35.97 ± 2.16 v. 45.80 ± 4.11, respectively). The apoptotic index was found to be lower (P < 0.05) for control blastocysts than that for transgenic blastocysts. However, the total cell number was similar (P < 0.05) among transgenic and control cloned blastocysts. Thus, transgenic cells, and subsequently transgenic embryos containing the human insulin gene, were successfully produced and transferred in recipients. In the future, these may be used for production of transgenic buffalo expressing human insulin in its milk and thus can be further utilised in large-scale production of human insulin.

Abstract
RationalePulmonary arterial hypertension (PAH) is a severe, progressive disease characterized by increased pulmonary arterial pressure and resistance due in part to uncontrolled vascular remodeling. The mechanisms contributing to vascular remodeling in PAH are poorly understood and involve rampant pulmonary artery smooth muscle cell (PASMC) proliferation. We recently demonstrated the important role of sphingosine kinase 1 (SphK1), a lipid kinase producing pro-proliferative sphingosine-1-phosphate (S1P), in the development of pulmonary vascular remodeling in PAH. However, the regulatory processes involved in upregulation of SphK1 in this disease are unknown.ObjectiveIn this study, we aimed to identify novel molecular mechanisms governing the regulation of SphK1 expression, with a focus on microRNA (miR). Using both in vitro studies in pulmonary artery smooth muscle cells (PASMCs) and an in vivo mouse model of experimental hypoxia-mediated pulmonary hypertension (HPH), we explored the role of miR in controlling SphK1 expression in the development of pulmonary vascular remodeling.Methods and ResultsIn silico analysis identified hsa-miR-1-3p (miR-1) as a candidate targeting SphK1. We demonstrate miR-1 is down-regulated by hypoxia in human PASMCs and in lung tissues of mice with HPH, coinciding with upregulation of SphK1 expression. PASMCs isolated from patients with PAH had significantly reduced expression of miR-1. Transfection of human PASMCs with miR-1 mimics significantly attenuated activity of a SphK1-3'-UTR luciferase reporter construct and SphK1 protein expression. miR-1 overexpression in human PASMCs also inhibited proliferation and migration under normoxic and hypoxic conditions, both important in pathogenic vascular remodeling in PAH. Finally, we demonstrated that intravenous administration of miR-1 mimics prevents the development of experimental HPH in mice and attenuates induction of SphK1 in PASMCs.ConclusionThese data demonstrate that miR-1 expression in reduced in PASMCs from PAH patients, is modulated by hypoxia, and regulates the expression of SphK1. Key phenotypic aspects of vascular remodeling are influenced by miR-1 and its overexpression can prevent the development of HPH in mice. These studies further our understanding of the mechanisms underlying pathogenic pulmonary vascular remodeling in PAH and could lead to novel therapeutic targets.Supported by grants NIH/NHLBI R01 HL127342 and R01 HL111656 to RFM, NIH/NHLBI P01 HL98050 and R01 HL127342 to VN, American Heart Association Predoctoral Fellowship (15PRE2190004) to JRS, and NIH/NLHBI NRSA F30 Fellowship (FHL128034A) to JRS.

Abstract
RationaleWe have previously shown that Nampt, which regulates intracellular NAD levels and cellular redox state, regulates histone deacetylases and inhibits apoptosis, is significantly upregulated in patients with pulmonary arterial hypertension (PAH). The aims of this study were to determine (1) whether Nampt+/− mice are protected from hypoxia-mediated pulmonary hypertension (HPH), (2) whether pharmacological inhibition of Nampt could attenuate monocrotaline (MCT)-induced pulmonary hypertension (PH) in rats. In addition, we hypothesized that Nampt secreted from pulmonary artery endothelial cells (PAECs) or overexpressing Nampt in pulmonary artery smooth muscle cells (PASMCs) may promote PASMC proliferation via upregulation of calcium signaling pathway, which plays a role in cell proliferation and vascular constriction.MethodsNampt+/− mice and their WT siblings (male, 7-wk old) were exposed to a hypoxia chamber with 10% O2 for four weeks. Male Sprague-Dawley rats (n=6 per group) received one dose of MCT (60 mg/kg), IP. They were administrated with FK866 (an inhibitor of Nampt enzymatic activity) (2.5 mg/kg, IP, twice daily for 2wks) two weeks after MCT. Right ventricular systolic pressure (RVSP) was determined with a pressure transducer catheter. The right ventricle: left ventricle+septum (RV/LV+S) ratio was calculated. In a cell culture model, hPASMCs were stimulated with recombinant Nampt (25 mg/ml) for 6 hrs and 48 hrs. [Ca2+]cyt was measured in PASMC loaded with flura-2/AM (4mM) in a fluorescence microscope and cyclepiazonic acid (CPA, a specific Ca2+-ATPase inhibitor) was used to induce store-operated calcium entry (SOCE). In addition, BrdU assays were conducted to examine rNampt or overexpressing Nampt can promote PASMC proliferation or Nampt secreted from PAECs isolated from PAH patients stimulates more PASMC proliferation than from healthy controls.ResultsAdministration of FK866 reversed established PH (RVSP [mm Hg] 19.77±0.80 [control] vs 51.24±4.35 [MCT] vs 34.45±3.49 [MCT+FK866], p<0.05 ) and RVH (0.25±0.0013 vs 0.60±0.019 vs 0.43±0.022, p<0.01). In PASMCs, short (6 hrs) and long (48 hrs) treatment with recombinant PBEF enhanced SOCE which is involved in sustained pulmonary vasoconstriction and PASMC proliferation. rNampt promotes PASMC proliferation in a dose dependent manner. PAECs from PAH patients secreted more Nampt which stimulates more PASMC proliferation compared to healthy controls. Overexpressed Nampt promotes PASMC proliferation. Inhibition of Nampt via FK866 attenuates rNampt-, Nampt overexpressed or PAEC-secreted Nampt – mediated PASMC proliferation.ConclusionInhibition of Nampt attenuates hypoxia-mediated PH in mice or MCT-induced PH in rats. Nampt may play a role in vascular remodeling via regulation of calcium signaling pathway. These data suggest that Nampt inhibition could be a potential therapeutic target for PH.

Abstract
Background: Evidence has been generated that various anticonvulsant agents provide relief of several chronic pain syndromes and therefore as an alternative to opioids, nonsteroidal anti-inflammatory, and tricyclic antidepressant drugs in the treatment of neuropathic pain. The results of these studies thus raise the question of whether all anticonvulsant drugs or particular mechanistic classes may be efficacious in the treatment of neuropathic pain syndromes. Aim: The aim was to compare the clinically used anticonvulsant drugs which are differ in their mechanism of action in a chronic pain model, the chronic constriction injury, in order to determine if all anticonvulsants or only particular mechanistic classes of anticonvulsants are analgesic. Materials and Methods: The study included zonisamide, ethosuximide and pregabalin. All compounds were anticonvulsant with diverse mechanism of actions. The peripheral neuropathic pain was induced by chronic constriction injury of the sciatic nerve in male Sprague-Dawley rats. Zonisamide (80 and 40 mg/kg), ethosuximide (300 and 100 mg/kg), pregabalin (50 and 20 mg/kg), and saline was administered intraperitoneally in respective groups in a blinded, randomized manner from postoperative day (POD) 7-13. Paw withdrawal duration to spontaneous pain, chemical allodynia and mechanical hyperalgesia and paw withdrawal latency to mechanical allodynia and thermal hyperalgesia were tested before drug administration on POD7 and after administration on POD 7, 9, 11 and 13. Results: The present study suggests that these drugs could provide an effective alternative in the treatment of neuropathic pain. However, zonisamide and pregabalin appears to have suitable efficacy to treat a wide spectrum of neuropathic pain condition. Conclusion: The present findings suggest that the inhibition of N-type calcium channels or voltage-gated sodium and T-type calcium channels provides better analgesic potential instead of inhibition of T-type calcium channels alone.

Abstract
CONTEXT Guggulipid is a neutral fraction of ethyl acetate extract of gum resin of the tree Commiphora mukul Engl. (Burseraceae) and used in Ayurvedic medicine for treatment of neurological disorders. OBJECTIVES The present study was undertaken to assess the antiallodynic and antihyperalgesic activities of guggulipid in rats. MATERIALS AND METHODS The screening study included the CCI and L5-L6 SNL models of neuropathic pain. Guggulipid (100 and 50 mg/kg) or saline was administered intraperitoneally in a blinded, randomized manner from postoperative day (POD) 7 to 13. Paw withdrawal duration (PWD) to spontaneous pain, chemical allodynia and mechanical hyperalgesia and paw withdrawal latency (PWL) to mechanical allodynia and thermal hyperalgesia were tested before surgery, before and after guggulipid or saline administration (from POD7 to 13) and after the withdrawal of treatment (from POD14 to 20). RESULTS The activity profiles of the different doses of guggulipid were found to vary with time. In CCI rats, guggulipid (100 and 50 mg/kg) significantly (p < 0.05) reduced the spontaneous pain, mechanical allodynia and mechanical and thermal hyperalgesia responses and the LD50 of guggulipid was 1600 mg/kg. In SNL rats, both doses of guggulipid were found to be ineffective in reversing the spontaneous pain but showing antiallodynic and antihyperalgesic activity. DISCUSSION AND CONCLUSION The results demonstrated that guggulipid produce antinociception in the peripheral nerve injury (CCI and SNL) models of neuropathic pain. The underlying mechanisms are expected to be modulating microglial activation occurring due to peripheral nerve injury.

Abstract
This study examined the effects of supplementation of ES-like cell culture medium with bone morphogenetic protein (BMP)-4 (0, 10, 20 or 100 ng/ml) or Noggin (250, 500 or 750 ng/ml) or TGF-β1 (0, 0.1, 1 or 10 ng/ml) or SB431542 (0, 10, 25 or 50 μm), an inhibitor of TGF-β1 signalling, on survival, colony area and expression level of pluripotency genes in buffalo ES-like cells at passage 40-80, under different culture conditions. BMP-4 supplementation significantly reduced (p < 0.05) colony survival rate, percentage increase in colony area and relative mRNA abundance of OCT4, whereas that of NANOG and SOX-2 was increased significantly (p < 0.05). Noggin supplementation did not affect the colony survival rate and percentage increase in colony area in the presence of FGF-2 and LIF. In the presence of FGF-2 alone, it significantly reduced (p < 0.05) the relative mRNA abundance of OCT4 and SOX-2 and increased (p < 0.05) that of NANOG. Supplementation with TGF-β1 at 1.0 ng/ml but not at other concentrations increased colony survival rate but had no effect on percentage increase in colony area at any concentration. Supplementation with SB-431542 decreased (p < 0.05) colony survival rate at 50 μm but not at other concentrations. The percentage increase in colony area was lower (p < 0.05) with 10 μm SB-431542 than that in the controls, whereas at higher concentrations of 25 or 50 μm, SB-431542 decreased (p < 0.05) the colony size instead of increasing it. In conclusion, these results suggest that BMP-4 induces differentiation in buffalo ES-like cells, whereas TGF-β/activin/nodal pathway may not be playing a crucial role in maintaining pluripotency in these cells.

Abstract
INTRODUCTION Colonoscopy is a safe procedure that is performed routinely worldwide. There is, however, a small but significant risk of splenic injury that is often under-recognized. Due to a lack of awareness about this injury, the diagnosis may be delayed, which can lead to an increased risk of morbidity as well as mortality. This paper presents a comprehensive review of the medical literature on colonoscopy-associated splenic injury and describes the clinical presentation and management of this rare but potentially life-threatening complication. MATERIALS AND METHODS A comprehensive literature search identified 102 patients worldwide, including patients from our experience, with splenic injury during colonoscopy. A meta-regression analysis was completed using a mixed generalized linear model for repeated measures to identify risk factors for this rare complication. RESULTS A total of 75 articles were identified and 102 patients were studied. The majority of the papers were in English (92 %). Only 23.4 % of patients (26/102) were reported prior to the year 2000. Among the patients reported after the year 2000, the majority (84.2 %, 64/76) were reported after 2005. There were more females (76.5 %), median age was 65 years (range, 29-90 years), and most of the colonoscopies were performed without difficulty (66.6 %). Nearly 67 % of patients presented within 24 h of colonoscopy with complaints ranging from abdominal pain to dizziness. The most common symptom was left upper quadrant pain (58 %), and CT scan was found to be the most sensitive tool for diagnosis. Seventy-three patients underwent operative intervention; 96 % of these were treated with splenectomy. Hemoglobin drop of more than 3 gm/dL was identified as the only significant predictor of operative intervention. The overall mortality rate was 5 %. CONCLUSION Splenic injury during colonoscopy is rare; however, it is associated with significant morbidity and mortality. Splenic injury warrants a high degree of clinical suspicion critical to prompt diagnosis, and early surgical consultation is warranted.

Abstract
Foreign body aspiration can be a life-threatening event especially in young children because they have smaller diameters of airway lumen, moreover, the delay in the diagnosis and subsequent therapeutic intervention can further increase the risk of morbidity.(1, 2) A retained foreign body can result in inflammatory response and granulation tissue formation around the object which make the foreign body removal difficult.(3) In such situations surgical intervention is usually needed but with interventional pulmonology modalities we can restrict the need for surgery.(4) Rigid bronchoscopy under general anaesthesia is the gold standard of diagnosis and management of foreign body aspiration.(1) However, nowadays flexible bronchoscopy is more widely available and most pulmonary physicians are trained in its use so it can be used to remove such foreign bodies. We hereby report a case of a neglected foreign body which remained in the bronchus of a child for 11 days, successfully removed by flexible bronchoscopy.

Abstract
An acceptable treatment approach for early childhood caries in the past may not necessarily be the best treatment option for our young patients today. Technological advances in dental materials and the approach to their use need to be considered, and the introduction of new adhesive systems, restorative materials, and the approach toward treating these teeth has yielded convincing results. Two such clinical case reports where polyethylene fibers were used as intra-canal posts and to splint the pontic fabricated with polyethylene fibers reinforced composite are reported.

Abstract
AIMS To find the prevalence of cardiovascular risk factors in type-2 diabetics without manifestations of overt coronary heart disease and to estimate the prevalence of silent myocardial ischaemia in these patients. METHODS Seventy seven patients of type 2 diabetes were recruited for the study (one patient lost after recruitment; 76 completed the study). History and physical examination were recorded. Laboratory investigations included fasting and 2-hour post-prandial blood sugar, blood urea, serum creatinine, lipid profile, glycated haemoglobin, and microalbuminuria. Ultrasonographic scanning of the carotid arteries was performed to measure the carotid IMT. For identification of cases of silent ischaemia, treadmill test (TMT) was performed. RESULTS The study group was divided into a non-CAD group (n=54), and a silent CAD group (n=22). Twenty-two diabetics were found to have silent CAD as evidenced by a positive TMT result (28.9%). The prevalence of silent myocardial ischaemia was almost similar in both males and females. Serum LDL levels more than 140 mg% had a significant correlation with the prevalence of silent CAD (p = 0.04). The difference in CCA-IMT values was found to be statistically significant between the silent CAD and non-CAD groups (p = 0.019). CONCLUSION High LDL level and greater carotid intima-media thickness are particularly important parameters that can predict if a patient of type 2 diabetes is at risk for silent ischaemia. A high carotid IMT is a surrogate and reliable marker of higher risk of CAD amongst type 2 diabetic patients, even in those without overt CAD. The study also underlines the utility of carotid IMT as a simple, non-invasive, safe, and cheap screening test for the assessment of risk of CAD in type 2 diabetics.

Abstract
AIMS To compare the carotid intimal-medial thickness in type 2 diabetics with and without coronary artery disease (CAD), and to correlate the intimal-medial thickness (IMT) with known coronary risk factors. METHODS One hundred and eleven patients of type 2 diabetes were recruited for the study. History and physical examination were recorded. Laboratory investigations included fasting and 2-hour post-prandial blood sugar, blood urea, serum creatinine, lipid profile, glycated haemoglobin, and microalbuminuria. Ultrasonographic scanning of the carotid arteries was performed to measure the carotid IMT. For identification of cases of silent ischaemia, treadmill test (TMT) was performed. RESULTS The study group was divided into a non-CAD group (n=40), and a CAD group (n=71). The mean carotid IMT of the group as a whole, was 0.840 +/- 0.2 mm. The mean carotid IMT was significantly higher (p<0.0001) in type 2 diabetics with CAD (both overt and silent) than in those without CAD. In diabetics with CAD, the systolic blood pressure, diastolic blood pressure and triglycerides were found to be predictors of high mean carotid IMT. On subgroup analysis of the cases with silent ischaemia, the variables affecting carotid IMT were serum creatinine, total cholesterol, microalbuminuria/proteinuria, serum triglyceride levels, and diastolic blood pressure. CONCLUSION A high carotid IMT is a surrogate and reliable marker of higher risk of CAD amongst type 2 diabetic patients, even in those without overt CAD. The study underlines the utility of carotid IMT as a simple, non-invasive, safe, and cheap screening test for the assessment of risk/prognosis of CAD in type 2 diabetics. We have also demonstrated the usefulness of measuring IMT, as a means to detect silent CAD among type 2 diabetics.

Abstract
Intrusion of immature permanent anterior teeth presents a great dilemma due to variety of treatment options. The ideal treatment option is the one with least probability of developing complications like external root resorption, obliteration of pulp canal, marginal bone loss etc. This paper presents a case report with treatment strategy of repositioning, splinting, successfully attempted apexification and obturation of a completely intruded immature permanent central incisor. Excellent healing with no post-operative complications even after 10 months of follow up.

Abstract
AIMS AND OBJECTIVE Ultrasonographic determination of gallbladder volume in diabetics [both type I and type 2], it's comparison with a control group, and correlation of gallbladder volume in diabetics with parameters such as age, sex, body mass index, parity, hyperlipidaemia, and autonomic neuropathy. MATERIALS AND METHOD Ninety one cases of diabetes mellitus and 40 healthy controls were recruited for the study. A detailed history and physical examination were recorded. Laboratory investigations done were--fasting and postprandial blood sugar, glycosylated haemoglobin, microalbuminuria, and serum lipid profile. Autonomic neuropathy was determined by using simple non-invasive bedside tests. Fasting gallbladder volume was measured by ultrasonography (calculated by ellipsoid formula). RESULTS The mean fasting gallbladder volume was 18.20 +/- 2.54 ml in type I diabetics and 25.87 +/- 13.90 ml in type 2 diabetics, with a minimum value of 9.30 ml and maximum value of 88 ml. When type 2 diabetics were subgrouped according to the presence of autonomic neuropathy, higher gallbladder volumes were seen in patients with autonomic neuropathy. CONCLUSIONS Cholecystomegaly, to a significant degree, was found in type 2 diabetics in the present study. It was significantly correlated with age, body mass index, and the severity of autonomic neuropathy. In male type 2 diabetics, gallbladder volume was significantly correlated with LDL cholesterol levels. In female type 2 diabetics, gallbladder volume was significantly correlated with waist-hip ratio. Gallbladder volume also had significant correlation with proliferative diabetic retinopathy, but not with glycaemic control, microalbuminuria, hypertension, or the duration of diabetes.

Abstract
Unripe Banana (Plantain) is used in South India as a bland diet for peptic ulcer patients. Flour made of plantain is quite often prescribed in dyspepsia in this part of the country. This has led to the belief that ripe banana may also be a bland fruit. However, it was observed by the Senior Author that ripe banana does produce symptoms of hyperacidity. Hence a study was undertaken to assess whether ripe banana is a bland food or not. A total of 115 patients entered the study. 89 individuals had no GIT symptoms, 15 patients had proved peptic ulcer while 11 patients had non-ulcer acid dyspepsia. The gastric residue was emptied by a nasogastric tube after a night fast. Patients were then given 80 gms. of banana or porridge on two different days. Then consecutive 15 minute samples of gastric juice were collected and submitted for estimation of acid output in mEq/l. It was observed that gastric acid values were higher following banana as compared to porridge and the difference was statistically significant (p < 0.001). It was was thus concluded that ripe banana is not a bland food. It should not be recommended as a part of bland diet for patients of acid peptic disease.

Abstract
Since hapten inhibition of precipitation is relatively time consuming, we have developed a hapten inhibition of adsorption assay to explore the sugar binding specificity of the Sophora japonica lectin. Adsorbents were prepared with Sephadex and p-aminophenyl beta-D-galactopyranoside using the CNBr procedure. The ability of simple saccharides to inhibit the binding of lectin to the adsorbent was performed employing a fixed amount of adsorption with respect to the logarithm of micromoles of inhibitor yielded sigmoid shaped curves. The quantities of various saccharides required to cause 50% inhibition of the lectin--adsorbent interaction relative to D-galactose were within+/-5% of the relative inhibiting potencies of the sugars in
