Background: Anxiety disorders are the most prevalent class of psychiatric condition. Medications commonly given for treatment can elicit several central nervous system (CNS) side-effects that patients find difficult to tolerate. So there is a need for new pharmacotherapeutic approaches to treat anxiety with greater efficacy and fewer side effects. Hence this study has been taken up to evaluate the anxiolytic effect of furosemide at three different doses (75mg/kg, 150mg/kg and 200mg/kg) in Albino rats.Methods: After obtaining approval from the institutional animal ethical committee 30 Albino rats weighing about 150-200gm were taken and divided into 5 groups of 6 rats each. Group 1: Normal Saline 10ml/kg (control); Group 2: Diazepam 2mg/kg (standard); Group 3: Furosemide 150mg/kg (test group 1); Group 4: Furosemide 200mg/kg (test group 2); Group 5: Furosemide 75mg/kg + Diazepam 1mg/kg (sub threshold dose). The anxiolytic activity of furosemide was tested by elevated plus maze and digital actophotometer models. Data was analysed using one way ANOVA followed by Posthoc Tukey’s test.Results: Furosemide (150mg/kg and 200mg/kg) have shown significant increase in open arm entries (p<0.05) and time spent in open arm (p<0.05) compared to control. Also furosemide (150mg/kg and 200mg/kg) have shown statistically significant decrease in locomotor activity (p<0.05) compared to control in actophotometer model. Potentiation of time spent and number of entries in open arm and decrease in locomotor activity were noticed when sub threshold doses of combination of diazepam and furosemide were used.Conclusions: These results suggest that furosemide possesses significant anxiolytic activity at both the doses. Furosemide given in sub threshold dose potentiates the antianxiety effect of sub threshold dose of diazepam when used in combination. Hence, after further studies, furosemide can be used as an anxiolytic drug.

Coleus forskohlii is an important ancient root drug of Indian origin, commonly known as gander in indian ayurvedic system of medicine. A lot of research work has been done on Coleus forskohlii regarding various cardiovascular disorders but no work has been done to find out its cardioprotective activity. Wistar albino rats were divided into five main groups having 5 animal each: Group 1 termed as Normal control (NC) received 0.5ml of normal saline throughout experimental period and served as control. Group 2 termed as Isoprenaline group (ISO) received 0.5ml of normal saline for 28 day and received Isoprenaline (85mg/kg, s.c.) on 29th and 30th day at an interval of 24 hours. Group 3 termed as Standard group (STD) received Metoprolol (pure) (10 mg/kg/day, p.o.) for 28 day and received Isoprenaline (85mg/kg, s.c.) on 29th and 30th day at an interval of 24 hours. Group 4 termed as Test group 1 (TG 1) and Group 5 termed as Test group 2 (TG 2) received Coleus forskohlii (50 mg/kg/day, p.o.) (100 mg/kg/day, p.o.) for 28 day and received Isoprenaline (85mg/kg, s.c.) on 29th and 30th day at an interval of 24 hours respectively. The experiment was terminated on 31st day and animal were sacrificed by cervical decapitation after an overnight fast. Blood was collected for estimation of biochemical parameter and heart was dissected out for grading, heart/weight ratio and histopathological examination.the the level of marker enzyme in serum as AST, ALT, LDH, CK, Troponin-I were significantly decreased (P 0.001) in rats pretreated with Coleus forskohlii when compared to that of group which received isoprenaline alone. Further, histopathological examination showed the reduction of necrosis, edema and inflammation following Coleus forskohlii pretreatment. Based on present findings, it is concluded that Coleus forskohliil may be a potential preventive and therapeutic agent against the myocardial necrosis associated ischemic heart disease.

Introduction: Removable dentures are used by 20% of the population. These may be accompanied by denture stomatitis in 15-70% of patients. The choice of the optimal cleansing agent for removable dental prostheses is of high significance. Aim: The aim of our research was to study the influence of removable denture cleansing products on the adhesion of microorganisms and yeast. Materials and Methods: We manufactured 144 specimens of standardized round shape with a diameter of 10 mm from 4 types of modern polymeric materials used by prosthetic dentistry to produce removable dentures, 12 specimens of each material were placed into suspensions of bacterial cultures of Staphylococcus aureus, Escherichia coli, Candida albicans, then into “ClearaSept” (Test group 1), “Рrotefix active cleanser” (Test group 2), saline solution (Control group), followed by nutrient media. The adhesion index was calculated and analyzed. Results: There was no reliable lowering of adhesion index of Staphylococcus Aureus to all materials detected in Test group 1 (U=6, p>0.05 for Bio XS; U=8, p>0.05 for Dental D, Denotokeep Peek, Vertex Rapid Simplified). In Test group 2, the adhesion index of Staphylococcus Aureus reliably decreased to all materials compared to the Control group (U=0, p≤0.01). The adhesion index of Candida albicans and Escherichia coli to all materials in Test group 1 had a minor to moderate reliable reduction compared to the Control group (U=0, p≤0.01). Test group 2 showed a significant reliable decrease in Candida albicans and Escherichia coli adhesion index to all materials in comparison with the Control group (U=0, p≤0.01). Conclusion: The research showed an unreliable or minor and moderate reliable decrease in microorganisms adhesion index depending on the microorganism species after treatment of denture material specimens by antibacterial soap “ClearaSept” and a reliable significant decrease in microbial and yeast adhesion after application of Protefix active cleaner solution, which demonstrates a more significant antimicrobial effect in comparison to “ClearaSept” against Staphylococcus aureus, Escherichia coli, and Candida albicans.

Abstract Background Increasing rates of breast cancer screening have been associated with an increasing frequency of non-palpable breast lesions detection. Preoperative breast lesion localization is essential for optimizing excision accuracy. This study aimed to evaluate the efficacy and safety of indocyanine green (ICG) hyaluronic acid injection as a novel mixture for localization. Methods We performed a prospective clinical trial with female patients who underwent surgery for non-palpable breast lesions. All patients were sequentially assigned to the control group (localization with activated charcoal), Test Group 1 (ICG-hyaluronic acid mixture 0.1 mL), or Test Group 2 (ICG-hyaluronic acid mixture 0.2 mL) by 1:1:1 ratio. Results A total of 44 patients were eligible for this study (Control Group = 14, Test Group 1 = 15, Test Group 2 = 15 patients). Fibroadenoma (n = 17, 38.6%) accounted for the largest proportion of diagnoses, and five patients (11.4%) were diagnosed with malignancies. There were no statistically significant differences in baseline characteristics among the three groups. The marking rate was over 86% in all groups, with no significant intergroup differences. Skin pigmentation was only observed in the control group. The mean accuracy of resection (the greatest diameter of the excised specimen divided by the greatest diameter of the preoperative lesion as observed using ultrasonography, with values closer to 1 reflecting a higher accuracy) was 3.7 in the control group, 2.2 in Test Group 1, and 2.1 in Test Group 2 (p = 0.037 between Controls and Test Group 1, p = 0.744 between Test Group 1 and Test Group 2, and p = 0.026 between Controls and Test Group 2). Conclusion ICG-hyaluronic acid injection is a novel method that was shown to accurately localize non-palpable breast lesions and was associated with no skin pigmentation. Further research is required to apply this method to malignant breast lesions. Trial registration “A Multicenter Open-label, Parallel, Phase 2 Clinical Trial to Evaluate the Efficacy and Safety of LuminoMark™ Inj. (Conc. for Fluorescence) Localization in Patients with Non-palpable Breast Lesions” was prospectively registered as a trial (ClinicalTrials. gov Identifier: NCT03743259, date of registration: May 29, 2018, https://clinicaltrials.gov/ct2/show/NCT03743259)

Background: Labour is the most perilous journey a woman has to undertake. Painless and short labour is desired by every woman and is a constant aim for obstetrician.Objective: To analyze and compare the efficacy and safety of drotaverine and valethamate with control group on improving cervical dilatation and promoting progress of labour. Method: Three hundred demographically similar women, both primigravida and multigravida with a term pregnancy in established labour were randomly divided into three groups. One hundred women (group 1) were given injection valethamate intramuscularly,100 women (group 2) were given drotaverine and the rest 100 (group 3) were not given any drug. Comparative analysis was carried out as regards to duration of first stage of labour, mode of delivery, maternal side effects and fetal outcome. Results: The mean duration of active phase of labour in group 1, 2 and 3 was 254.29±96.621 min, 178.31±73.412 min and 346.31±123.351 min respectively. The duration of injection to end of first stage of labour in valethamate and Drotaverine group was 228.12±84.626min and 168.89±69.576min respectively (p value<0.0001). The duration of injection to delivery in Valethamate was 249.13± 88.321 min and in Drotaverine was 192.56±75.479min (p value<0.0001). There were no serious maternal and fetal adverse effects in any group but minor side effects were more common in valethamate group. Conclusion: The reduction of the duration of the first stage of labour was apparently more in drotaverine group as compared to valethamate and control group. Drotaverine was found to be safe with minimal or no adverse effect on the mother and the fetus.

ABSTRACT Objective: To investigate the effect of experimental prenatal and postnatal hypothyroidism (HT) on the craniofacial structure in rats. Materials and Methods: Female Wistar albino rats were mated with males for fertilization. Pregnant rats were divided into three groups. Group 1 (methimazole [MMI]-induced prenatal hypothyroidism group) mother rats were given MMI water during and after pregnancy. Group 2 (MMI-induced postnatal hypothyroidism group) mother rats were given MMI water after pregnancy. After the breast-feeding period, group 1 and 2 rat pups received the same water as their lactating mothers drank. Group 3 (control group) pregnant rats and rat pups were given normal tap water. When the rat pups were 90 days of age, lateral cephalometric and posteroanterior films were taken under anesthesia. Results: Posteroanterior radiographs revealed that palatal, cranial, bizygomatic arch, and bigonial width measurements were significantly shorter in prenatal HT and postnatal HT groups compared to the control group (P &lt; .001). Intragroup comparisons in lateral cephalometric radiographs showed that, nearly all of the comparisons were statistically significant (P &lt; .05), with the exception of the Co-Gn, E-Pg/S-Gn measurements between the prenatal and postnatal HT groups. Conclusions: Sagittal and transverse measurements showed that untreated HT has detrimental effects on the growth of the maxilla and mandible.

Background: Poisoning is major health issue all over the world. Poisoning is one of basic causes for Out Hospital cardiac arrest (OHCA). P-OHCA (Poison induced Out Hospital cardiac arrest) can be prevented by immediate primary management. The agent for poisoning is unknown in most cases, which leads to difficulty deciding the emergency antidote. In Ayurveda Hridyavaranchikitsa (Cardio protection) is one of the treatment modalities mentioned in all types of poisoning as first aid treatment. Suvarna Gairik (Red ochre) is one of drugs mentioned for the cardioprotection. Snake bite and organophosphate poisoning are the threats to life in India. Doxorubicin is commonly used drug for Chemotherapy in malignancies, and its major side effect is cardiotoxicity. Hence these poisonings are included in study. Aim and Objective: Evaluation of cardioprotective activity of Suvarna Gairik (Red ochre) in cardiac biomarker like Lactate dehydrogenase, Creatinine phosphokinase, Alkaline transferase, Cardiac Troponins and Survival Time in Indian Cobra Envenomation, Aluminium phosphide poisoning and Doxorubicin cardiotoxicity in Albino Rats. Methodology: Animal study is designed. 56 wistar rats will be divided in 7 groups as Vehicle Control Group, Disease control Group -1 Indian Cobra envenomation, Disease control Group -2Aluminium Phosphide poisoning, Disease control Group -3 Inj. Doxorubicin induced cardiotoxicity, Test Group -1 Indian Cobra Envenomation and Suvarna gairik Test Group -2 Aluminium Phosphide poisoning and Suvarna gairik Test control Group 3- Inj. Doxorubicin cardiotoxicity and Suvarna gairik. Results: Outcome will be assessed in between groups and among groups. Conclusion: Suvarna Gairik (Red ochre) may show statistical significant cardioprotective activity.

Objectives: To evaluate the efficacy of postoperative analgesia, side effects and complications of caudal block with levobupivacaine 0.25% 1mL/kg for subumbilical surgery. Materials and methods: In a comparative cross-sectional descriptive study, sixty ASA I–II children less than 6 years old scheduled for elective subumbilical surgery were randomized to divide into 2 groups: group 1 (control group) were only used general anethesia with laryngeal mask, group 2 (levo group) were anesthetized under general anaesthesia with laryngeal mask and caudal block with levobupivacaine 0.25% 1mL/kg to relieve pain after surgery. The evaluation variables included the duration of postoperative analgesia, total analgesic used in 12 hours after surgery, FLACC score, Ramsay and Bromage score after extubation of laryngeal mask, side effects and complications. Results: The duration of postoperative analgesia in the caudal block group was 8.25 ± 1.48 hours, in the control group was 0.07 ± 0.37 hours. The total dose of acetaminophen and morphine after surgery in the control group were 574.50 mg ± 23.61mg and 3.94 ± 1.6 mg, while in the levo group were 251.25 mg ± 15.7 mg and 0 mg. In the levo group, at the recovery time, all patients had FLACC score ≤ 3 and most of the patients were co-operative and alert. No side effects occurred between two groups. Conclusion: caudal block for postoperative analgesia was a safe and effective analgesia technique for children. Key words: caudal block, levobupivacaine, subumbilical surgery, children, postoperative analgesia

Background: Most important adverse effect of NSAID is peptic ulceration. Even though H2 blockers and proton pump inhibitors are effective in preventing NSAID associated peptic ulceration, they are not without side effects. Hence there is a need for drugs which are effective in preventing NSAID induced peptic ulcer without producing side effects. Two plant products Aloe vera leaf extract and Aegle marmalos leaves are commonly used in Indian traditional medicine for treatment of peptic ulcers. Hence this study is undertaken to assess the antiulcerogenic potential of combination of these two drugs in comparison with ranitidine in preventing NSAID induced peptic ulcers.Methods: 18 albino rats were divided into 3 groups of 6 rats each. Group A: received ulcerogen only. Group B: pretreated with ranitidine before exposing to ulcerogen. Group C: pretreated with combination of Aloe vera and Aegle marmelos before exposing to ulcerogen. Two doses of indomethacin were administered at an interval of 15 hrs. Animals were sacrificed 6 hrs after the second dose of Indomethacin. Number of ulcers was noted, and ulcer index was calculated.Results: There was significant reduction in total score, mean score and ulcer index in ranitidine pretreated group and test compound group as compared to control group. Even though the total score and ulcer index in test group were lesser as compared to standard control group, it was not statistically significant.Conclusions: Combination of Aloe vera leaf extract and Aegle marmelos leaf extract produced very significant protection against indomethacin induced gastric ulcer.

Objective: The main objective of this study was to evaluate the antidiarrheal activity of Bunim bulbocastanum seeds extracts, to exploit the medicinal use of plant in the traditional system of medicine scientifically. Methods: The adult Wistar albino rats were divided in four groups, i.e. Group M1 (control group) receiving normal saline, group M2 (test group 1) receiving the 250 mg/kg Bunium bulbocastanum extract, group M2 (test group 2) receiving the 500 mg/kg Bunium bulbocastanum extract and group M4 (reference) receiving 3 mg/kg P. O Loperamide. Each group of mice with a bodyweight of 1 ml/100 g received castor oil. Mice were sacrificed and the distance traveled by the charcoal meal and the total length of the intestine was then measured. The peristaltic index and percentage of inhibition were calculated by using the formula. Results: It was found that in the castor oil-induced intestinal transit method extract produced a significant (p<0.0001) dose-dependent reduction in the distance traveled by charcoal meal comparable to the control peak effect was at the dose of 500 mg/kg (PI=12.06±3.38). Likewise, in the diarrheal dropping test, Bunium bulbocastanum extract causes a significant (p<0.05) dose-dependent reduction in the number of wet feces i.e. the mean wet of feces was decreased from 2.3±0.44 gm to 1.28±0.36 gm i.e. significantly different from that elicited by control (0.80±0.17 gm) (p=0.0081). However, there were no significant differences in inhibition at a dose of 250 mg/kg of extract. Conclusion: This study demonstrated that the crude methanol extract from B. bulbocastanum seeds possesses significant antidiarrheal property and the presence of various secondary metabolites. This justified the antidiarrheal use of plant in the traditional system of medicine.
