Abstract In order to quantitatively assess the effect of sample storage conditions on the body burden analysis of organic contaminants, a comparative analysis was carried out on the unionid mussel Elliptic complanata. The mussels were divided into two groups, each with distinct storage conditions, while Group A was kept in the freezer at −20°C, Group B was kept in the refrigerator for five days at 5°C. All the compounds present in the control were also present in Group B samples. Analysis of the organic contaminants in each of these two groups showed that for total PCB concentrations, the two treatments were not significantly different; however when compared individually 6 of the 13 PCB congeners showed significant differences. The observed differences were relatively small for individual PCB congeners (7.1 to 15.3%), higher for chlorobenzenes (10.5 to 36.4%), and yet higher for HCE (44.1%); the difference for HCE, although large is nevertheless not significant, even if only marginally so.

A total of 24, six weeks old mice were used to study the body weight and haemato-biochemical changes following administering of different haematinics (CuSO4, FeSO4 and Vitamin B12). The experiment was performed in Physiology laboratory, Department of Physiology, Faculty of Veterinary Science, Bangladesh Agricultural University, Mymensingh, from February to March 2006. They were randomly assigned to one of four equal groups (n = 6). In addition to normal rat pellets Group A was supplemented with CuSO4 @ 0.6mg/mice/day orally, Group B with FeSO4 @ 1.2mg/mice/day orally, and Group C with Vitamin B12 (Cytamin®, Glaxo) @ 0.004mg/mice intramuscularly at every 7 days. Group D was considered as control and was also supplemented with rat pellets. Increased body weight was observed in all haematinic treated mice but group B had a significant (p < 0.05) higher weight gain compared to the control. TEC and PCV increased significantly (p < 0.05) in all the treatment groups compared to the control. Statistically insignificant (p > 0.05) increase in TLC was also recorded in all the treated groups. Hb concentration increased for all the treatment groups. The ESR values of the experimental mice were negligible in first hour. The serum transaminases (SGPT and SGOT) increased in all treated groups but the difference in group A was significant (p < 0.05) compared to the control. Blood urea was recorded significantly (P < 0.01) higher for group A and lower for group C compared to the control. This study can be helpful to study the effect of particular haematinic on animal especially on simple stomach animal and human being as mice is used as human and animal model.

Agility have been defined by the capacity to retain or determine the location of body by shifting its direction rapidly in a sequence of movements. Agility, speed and explosive power are qualifying components of physical fitness and desirable athletic performance, and play a key role in most sports. Agility can enhance the coordination and regulation of locations of the body throughout movement. Objective: To study the efficacy of the 6-weeks and 12-weeks Plyometric training on the agility in police cadets. Method: 40 Cadets aged above 18 years were grouped into two. A group continued their regular activities while rest underwent 2 sessions of plyometric training every week for 6 weeks, along with their daily activities. Analysis was then carried out with assessment of T-test Agility test, Illinois Agility Test, Edgren Side Step Test. Study duration is 6 months and intervention duration is 12-weeks, hence participants will be enrolled during first 3-months of study so 12 week intervention has been completed successfully. Assessment will be done on 1st day of visit then at the end of 6th week and again at the end of 12th week. Participants would have to perform 2 session of Plyometric Training per week in other group. Result: The results show that there is improvement the agility of the police cadets through the outcomes measures taken as a instrument to measure the difference in 1st day, 6th week and 12th week. There is decrease in time period of Agility T-test from 14.04±1.64 to 10.96±1.39 in group A and from 14.16±1.43 to 13.53±1.52 in group B. There is increase in steps of Edgren Side Step test from 34.95±4.84 to 40.93±4.17 in group A and from 34.97±4.17 to 36.31±4.34 in group B. There is decrease in time period of Illinois Agility test from 20.61±4.36 to 18.33±4.14 in group A and from 20.73±4.45 to 20.47±4.42 in group B. Conclusion: This study concludes that plyometric training intervention have improved the agility among the police cadets and it can be implemented among personnel’s from law enforcement agencies.

Background: Scabies is one of the most common skin diseases in our country. It is caused by the mite Sarcoptes scabiei var hominis, which is an ecto-parasite infesting the epidermis. Scabies is highly contagious. Prevalence is high in congested or densely populated areas. Individuals with close contact with an affected person should be treated with scabicidal which is available in both oral and topical formulations. The only oral but highly effective scabicidal known to date is Ivermectin. Amongst topical preparations, Permethrin 5 % cream is the treatment of choice. Objective: To evaluate the efficacy & safety of oral Ivermectin compared to topical Permethrin in the treatment of scabies. Methodology: This prospective, non-randomized study was conducted at the out-patient department of Dermatology and Venereology of Shaheed Suhrawardy Medical College & Hospital over a period of 6 months, from August 2016 to January 2017. The study population consisted of one hundred patients having scabies, enrolled according to inclusion criteria. They were divided into two groups. group A was subjected to oral Ivermectin and the group B to Permethrin 5% cream. Patients were followed up on day 7 and 14 for assessment of efficacy and safety. Result: The mean scoring with SD in group A (Ivermectin) and group B (Permethrin) were 8.26 ± 2.22 and 7.59 ± 2.01 respectively at the time of observation. The difference between the mean score of the two group is not significant (p=0.117) the mean scoring with SD in group A and group B were 4.54 ± 2.05 and 1.64 ± 1.84 respectively at 7thdays. The difference between the mean score of the two group is significant (p<0.001). The mean scoring with SD in group A and group B were 2.68± 2.35 and .36± 1.10 respectively at 14th day difference between the mean score of the group is significant (p<0.001). Conclusion: Topical application of permethrin 5% cream is more effective and safer than oral Ivermectin in the treatment of scabies. TAJ 2020; 33(1): 41-47

Without having a reaction time, the pandemic has caused an unprecedented transformation in universities around the world, leading to a revolution from structured models anchored in the conception of transmission of training towards a teaching approach-learning saved thanks to the incorporation of technology. This study aims to verify whether the pandemic situation has influenced the digital competence self-perception of students. Comparing two groups during the academic years 2019/2020 and 2020/2021, the instrument used is the questionnaire for digital competence “DigCompEdu Check-In” for future teachers. After the educational intervention, group A (before COVID-19) presented higher self-perceptions of competence than group B (during COVID-19); the pandemic situation caused by COVID-19 has negatively influenced students’ self-perception of their digital skills in the pretest in the different dimensions under study. Before receiving the training, the group that did not experience the pandemic enjoyed a higher self-perception of their competencies than the group that experienced the pandemic. The data obtained indicate that the difference exists, and that it is statistically significant, and may be a consequence of the clear relationship between self-perception and the way in which students face reality through their personal and subjective vision.

Abstract Background Repair of a perforated tympanic membrane (myringoplasty) can facilitate normal middle ear function, resist infection, and help re-establish normal hearing. Autogenous graft materials are the most popular graft materials used in myringoplasty because of their easy acceptability by the body. This study is conducted to compare between temporalis fascia graft and fascia lata graft in myringoplasty for patients with tubo-tympanic dry perforation. Results A total of 60 patients with persistent dry tympanic membrane perforation were included in our study during the period from January 2018 to May 2020. Patients underwent myringoplasty with temporalis fascia (30 patients as group A) or fascia lata (30 patients as group B). Patients were scheduled for follow-up visits concerning graft status, ear discharge, and audiograms. The mean postoperative air-bone gap in group A was 17.5 ± 4 after 1 month and 8.6 ± 6.9 after 3 months, while in group B, the mean postoperative air-bone gap was 17.6 ± 4.9 after 1 month and 9.4 ± 7.5 after 3 months. There was 90% success in graft uptake in group A, while there was 80% success in group B. Conclusion Using temporalis fascia is still the best and most trustworthy technique of myringoplasty compared to fascia lata graft. However, fascia lata can be a good alternative to temporalis fascia especially in cases of revision myringoplasty, ears having large perforation, or near-total perforation where the chances of residual perforation are high because of the limited margin of remnant tympanic membrane overlapping the graft.

Objectives: The main goal of this research was to determine the differences between the values of intraocular pressure (IOP) in the supine and sitting positions, and to assess the effect of age and cardiovascular parameters. Methods: Seventy-two healthy adults were enrolled and classified into age groups: 20–30 years (group A), 31–40 years (group B), and 41–71 years (group C). Corneal biometry and cardiovascular parameters, such as heart rate (HR), were measured. IOP measurements were taken in the sitting position (IOPS) and in the supine position (IOPL) using the iCare® Pro tonometer. Results: A significant difference between the IOPS and IOPL in the entire cohort was found ( p < 0.001). Regarding the age subgroups, a significant difference ( p < 0.001) between the IOPS and IOPL was obtained in group A (2.6 ± 1.6 mmHg) and group C (1.5 ± 1.3 mmHg). There were no significant differences in the IOPS between groups. The highest IOP values were obtained for group A. The correlations between HR and IOPS are statistically significant for group A and group B, and for HR and IOPL-S for group B only. Multivariate analysis showed that HR has a significant influence on the difference in IOP in the two body positions. Conclusion: A statistically significant difference between the effect of age and the values of IOPS and IOPL was shown. Cardiovascular parameters showed some relevant statistical dependencies, but with a rather marginal significance in young people. The influence of body position for the measurement of IOP for healthy subjects does not seem to matter, despite the fact that there are some dependencies that are statistically significant.

Background: Tonsillectomy is one of the most common surgical procedures performed worldwide by otorhinolaryngologists for different indications. Tonsillectomy is often performed as day-case surgery, which increases the demands of a satisfactory postoperative pain control and a low risk of early postoperative bleeding. Objective: The aim of the study was to compare the Monopolar diathermy and Dissection methods of tonsillectomy and evaluate their advantages and disadvantages during surgery, convalescence. Materials and Methods: Two hundred children were recruited for this study during the period of five years from January, 2014 to December, 2018 at Otolaryngology department of Khwaja Yunus Ali Medical College and Hospital (KYAMCH). Subjects between the age of 5 and 25 years listed for tonsillectomy were included. Subjects were recommended not to have aspirin within the 2 weeks before surgery. Results: The mean duration of operation was found 10.6±0.4 minutes in group A and 17.0±0.7 minutes in group B. The difference was statistically significant (p<0.05) between two groups. At 1st day, 11(11.0%) patients had throat pain in group A and 23(23.0%) in group B. At 2nd day, 14(14.0%) patients had throat pain in group A and 25(25.0%) in group B. Which were statistically significant (p<0.05) between two groups. Conclusion: The monopolar diathermy tonsillectomy appears to cause less bleeding, postoperative pain and less time consuming in compare with the dissection tonsillectomy although patients experience slightly more pain than dissection Method.

AbstractConstipation, obstructed defecation, and fecal incontinence are frequent complaints in multiple sclerosis. The literature on the pathophysiological mechanisms underlying these disorders is scant. Using anorectal manometry, we compared the anorectal function in patients with and without multiple sclerosis.136 patients referred from our Center for Multiple Sclerosis to the Coloproctology Outpatient Clinic, between January 2005 and December 2011, were enrolled. The patients were divided into four groups: multiple sclerosis patients with constipation (group A); multiple sclerosis patients with fecal incontinence (group B); non-multiple sclerosis patients with constipation (group C); non-multiple sclerosis patients with fecal incontinence (group D). Anorectal manometry was performed to measure: resting anal pressure; maximum squeeze pressure; rectoanal inhibitory reflex; filling pressure and urge pressure. The difference between resting anal pressure before and after maximum squeeze maneuvers was defined as the change in resting anal pressure calculated for each patient.ResultsGroup A patients were noted to have greater sphincter hypotonia at rest and during contraction compared with those in group C (p=0.02); the rectal sensitivity threshold was lower in group B than in group D patients (p=0.02). No voluntary postcontraction sphincter relaxation was observed in either group A or group B patients (p=0.891 and p=0.939, respectively).ConclusionsThe decrease in the difference in resting anal pressure before and after maximum squeeze maneuvers suggests post-contraction sphincter spasticity, indicating impaired pelvic floor coordination in multiple sclerosis patients. A knowledge of manometric alterations in such patients may be clinically relevant in the selection of patients for appropriate treatments and for planning targeted rehabilitation therapy.

This study was conducted in the Department of Anesthesiology, Holy Family Hospital Rawalpindi from 5 October 2011 to 5 April 2012 after approval of hospital ethics committee. Three hundred and eighteen patients fulfilling the inclusion criteria were selected in the study by non-probability consecutive sampling after taking informed written consent. Patients between the ages of 20 to 40 years were included, belonging to ASA class I and II, requiring General Anesthesia with Laryngeal Mask Airway for different surgical procedures. They were divided into two equal groups by computer generated random numbers. Group A comprised of one hundred and fifty eight patients in whom intravenous propofol was given for induction of anesthesia and Laryngeal mask insertion. Group B comprised of one hundred and fifty eight patients in whom inhalational induction with sevoflurane was done for Laryngeal mask insertion. Conduct of anesthesia was maintained similar in both groups. Cough and gag reflexes were observed in both groups at the time of Laryngeal mask insertion. Drug under study was said to be effective, if it is associated with no cough and gag reflex during Laryngeal mask insertion. All the data was analyzed by SPSS version 15. It was observed that 6.3% patients of group A (propofol) had positive cough reflex as compare to 13.2%% patients of group B (sevoflurane). The difference was statistically significant (p=0.038). While the incidence of gag reflex in group A was 8.2% and group B was 14.5%. But the difference was not found to be statistically significant (p=0.077). Propofol is more effective than sevoflurane for smooth LMA insertion during elective surgeries.DOI: http://dx.doi.org/10.3126/jcmc.v5i1.12562

Metabolism is the natural process of the body, which is necessary to maintenance of the homeostasis of an individual person. Everybody constitutions are always in the process of metabolism, which is a combination of Anabolism (Construction) and Catabolism (Deterioration). As Agni is prime factor for all the Chayapachayakriya. Medoroga, is one of the Metabolic disease, in which contributing factors are Agni, Ama along with Kaphapradhana Tridosha, Medodhathu. Due to various types of etiological factors, the Agni in the body gets vitiated and Jatharagnimandya occurs. By this Jatharagnimandya, Dhathuparinama will not occur properly. This will lead to Medoroga and further many other Upadravas. To correct these conditions, Ayurveda has many modes of therapies like Samshodhana, Samshamana. By these we can correct the metabolism from the root cause. Here 40 Subjects diagnosed with Medoroga w.s.r. to Hyperlipidemia fulfilling the Inclusion criteria were selected for study and randomly categorized into two groups as Group A and Group B each consisting of 20 subjects. For both groups Amapachana with Chitrakadi Vati, Sadhyosnehapana with Murchita Sarshapa Taila, Sarvanga Abhyanga with Murchita Tila Taila followed by Swedana. And Virechana was administered with Virechana Gulika. Than each group received two different Shamanoushadhi. So, the objective of the study is to establish the efficacy of Virechana along with Dashanga Guggulu and Virechana along with Shadushana Guggulu in the management of Medoroga.
