RESUMO
Abstract Introduction Obstructive sleep apnea (OSA) is a breathing disorder related to sleep that has a negative effect on the behavior and health of people around the globe. Chronic hypoxemia and variations in the concentration of oxygen in the blood noticed in OSA individuals may have adverse effects on the process of auditory transduction and transmission. Objective To assess the effect of OSA on hearing and to find out the parameters that have more influence on hearing recorded during polysomnography of patients with OSA. Methods The present is a hospital-based, observational, analytical, cross-sectional study conducted over a period of one year. After application of the exclusion criteria, the patients were then submitted to the application of the Berlin questionnaire, as well as polysomnography, impedance, and pure tone audiometry (PTA). Results A total of 58 individuals were studied. Age, gender, and height were comparable among cases and controls, while weight, body mass index (BMI), and neck circumference were significantly higher in cases in comparison to controls. The mean PTA was significantly higher at 10 kHz or higher frequencies in cases in comparison to controls. Conclusion We observed that there is evidence that the auditory mechanism is affected in OSA patients. We recommend early auditory screening of OSA patients for timely diagnosis and to raise awareness about its prevention.
RESUMO
In our daily lives, we have to perform multiple tasks in different areas. This leads people to two paths: carrying out the task as soon as possible or postponing it; the latter being part of the tendency to delay the start or completion of a task. This act also known as procrastination. procrastination is the characteristic or behavioural propensity to put off or delay completing a task or making decisions. Procrastination behavior is very common and a serious problem in the era we live in. Academic procrastination appears to be common in academic environments as students frequently put off their obligations without good reason and submit their work right up until the deadline. All levels of kids are impacted, and it may lead to major problems including declining grades and decreased wellbeing. The notion of academic procrastination, reasons why it occurs, negative effects of academic procrastination and several methods for dealing with it are all discussed in this article. It is suggested that some programs should be devised and executed to teach task-oriented coping strategies to students. For this one should reflect on the reasons why you procrastinate, your habits and thoughts that lead to procrastinating
RESUMO
Background: Low cardiac output is a common complication following cardiac surgery and it is associated with higher mortality in the pediatric population. A gold standard method for cardiac output (CO) monitoring in the pediatric population is lacking. The present study was conducted to validate cardiac output and cardiac index measured by transthoracic echocardiography and Pressure recording analytical method, a continuous pulse contour method, MostCare Up in postoperative pediatric cardiac surgical patients. Materials and Methods: This was a prospective observational clinical study conducted at a tertiary care hospital. A total of 23 pediatric patients weighed between 2 and 20 kg who had undergone elective cardiac surgery were included in the study. Results: Spearman抯 correlation coefficient of CO between transthoracic echocardiography (TTE) and Pressure Recording Analytical Method (PRAM) showed of positive correlation (r = 0.69, 95% Confidence interval 0.59?0.77, P < 0.0001) Linear regression equations for CO between TTE and PRAM were y = 0.55 + 0.88x (R2 = 0.46, P < 0.0001). (y = PRAM, x = TTE), respectively. Bland? Altman plot for CO between TTE and PRAM showed a bias of ?0.397 with limits of the agreement being ?2.01 to 1.22. Polar plot analysis showed an angular bias of 6.55� with radial limits of the agreement being ?21.46 to 34.58 for CO and angular bias of 6.22� with radial limits of the agreement being ?22.4 to 34.84 for CI. Conclusion: PRAM has shown good trending ability for cardiac output. However, values measured by PRAM are not interchangeable with the values measured by transthoracic echocardiography.
RESUMO
Purpose: Extraction of tear protein from Schirmer’s strip is a prerequisite for the proper identification and screening of biomarkers in dry eye disease. The study compares different methods of extraction of tear proteins from the Schirmer’s strip. Methods: Reflex tear was collected from healthy controls (HC; n = 12), Stevens–Johnson syndrome (SJS; n = 3) and dry eye disease (DED; n = 3) patients using capillary tube. This tear was used to measure the volume absorbed by Schirmer’s strip per microliter. Different buffers (6) were used to compare the protein yield from the Schirmer’s strip in four different conditions. The tear proteins extracted using the highest protein yield buffer were analyzed by mass spectrometry. Results: A linear relationship between the tear volume and wetting length was observed (r = 0.0.997, n = 6). The highest yield was observed after incubation of the Schirmer’s strip in 100 mM ammonium bicarbonate (ABC) with 0.25% Nonidet P?40(NP?40) at 4°C for an hour (P < 0.00005). The in?solution digestion of tear eluted in the above condition 100 Mm ABC + 0.25% NP?40 with one?hour incubation yielded a total of 2119 proteins in HC, SJS, and DED. The unique protein observed in SJS and DED was 0.6% and 17.9%, respectively. The significantly expressed proteins are associated with innate immune response, proteolysis, wound healing, and defense response. Conclusion: A method for extraction of protein from Schirmer’s strip was optimized for increase in protein yield from the tear sample. SJS and DED tear samples have unique protein signature. The study will aid in better design of tear protein?based experimental study.
RESUMO
Purpose: To describe the demographics, clinical profile, and outcomes of ocular siderosis in patients presenting to a multi?tier ophthalmology hospital network in India. Methods: This cross?sectional and hospital?based study included 3,082,727 new patients who presented between August 2010 and December 2021. Patients with a clinical diagnosis of ocular siderosis in at least one eye were included. Results: Overall, 58 eyes of 57 patients (0.002%) were diagnosed with ocular siderosis. The majority were men (96.49%) and had unilateral (98.25%) affliction. The most common age group at presentation was during the third decade of life with 24 patients (42.11%). A clear history of ocular trauma was documented in 47 patients (81.03%). Major clinical signs included corneal pigment deposition in nearly half of the eyes (27/58 eyes, 46.55%), corneal scar (20/58 eyes, 34.48%), cataract (22/58 eyes, 37.93%) and retinal detachment (11/58 eyes, 18.96%). The intraocular foreign body (IOFB) was anatomically localized in a majority of the eyes (i.e., 45/58 eyes, 77.59%). The most common location of the IOFB was in the posterior segment (22/58 eyes, 37.93%). The eyes that underwent a vitreoretinal surgery with removal of IOFB had a slightly better BCVA (1.0 ± 1.01) when compared to eyes with non?removal of IOFB (1.58 ± 1.00). Conclusion: Ocular siderosis is a rare sight?threatening entity, with half of the affected eyes exhibiting severe visual impairment. Majority of the eyes in ocular siderosis will have a detectable IOFB. Surgical removal of IOFB may lead to a better visual gain when compared to non?removal.
RESUMO
Concerns about the effect of activities that need the use of alternative fuels, as well as a growth in demand for clean energy, have made biofuels research more well-known, and so began the search for oilseed plants that can be used to make biodiesel. Present research was carried out the aloe vera oil is used as a biodiesel in diesel engine. Because aloe vera oil having higher calorific value compare to other sources. Potassium hydroxide catalyst was used for transesterification process, which has lesser cost and more availability. And also, in this work conducted diesel engine experiments using four different biodiesel blends (B20, B40, B60, B100) and diesel fuel. Additionally, to reduce the emission nano particles (TiO2) was blended with optimal biodiesel blend (B20). The performance and emission characteristics were conducted with different biodiesel blends. In this blends, B20+ TiO2 blend gives good performance and reduction in emissions compared to other biodiesel blends.
RESUMO
Purpose: To report the demographic profile of patients registered through e?Sanjeevani OPD seeking teleophthalmology services. Methods: This was a cross?sectional data analysis of patients with ocular complaints registered through the e?Sanjeevani platform at a tertiary care center. It was a doctor?to?doctor consultation, where teleophthalmology consultants provided teleconsultation services at subcenters (SCs), primary health centers (PHCs), and community health centers (CHCs). Data regarding the patient’s age, gender, residential address, provisional diagnosis, and treatment prescribed were recorded from May 2021 to February 2022 (9 months). Results: In total, 5138 patients were teleconsulted from the mean age of the patients was 37.64 ± 19.34 years. Among these patients, 44% were males and 56% were females. Most of the teleconsultation calls were made from Palwal district (19.8%), followed by Hisar (14.5%) and Sonipat. The most common provisional diagnosis was dry eyes (21%), followed by allergic conjunctivitis (18%), refractive error (15%), and cataract (14%). These constituted approximately 70% of the diagnosis made through teleconsultations. The rest of the eye problems were diagnosed as stye, blepharitis, nasolacrimal duct obstruction, pterygium, subconjunctival hemorrhage, etc., The majority of the patients were managed medically (56.6%) and approximately 11.6% of the patients were referred for surgical intervention. Conclusion: e?Sanjeevani is an effective way to provide teleconsultations to patients in remote locations. The majority of the patients seeking ophthalmology consultations can be managed conservatively. Patients requiring surgical intervention can be referred timely, thus avoiding any delay in treatment
RESUMO
Abstract Introduction The Montgomery T-tube is a device used as a combined tracheal stent and tracheostomy tube to prevent post-operative tracheal stenosis. Objectives The purpose of this retrospective study is to evaluate the outcome following Montgomery T-tube stenting performed in for neck and airway injury in patients with acute blunt laryngotracheal trauma over a period of 12 years. Methods Between 2005 and 2017, 19 patients with acute blunt laryngotracheal trauma underwent Montgomery T-tube stenting. All 19 laryngotracheal trauma patients had undergone a preoperative tracheostomy in the emergency department by an ENT surgeon. Montgomery T-tube stenting was done later through an external approach. The follow up period ranged from 2 to 10 years. The Montgomery T-tube was removed after a period ranging from 6 months to 1½ year. Results The majority of patients in the study were in the age group of 21-30 years. A preoperative tracheostomy was done in all 19 patients. All patients except 3 underwent successful decannulation, and experienced long-term satisfactory result. Conclusion Management of acute blunt laryngotracheal trauma is a challenging problem that demands a multidisciplinary approach. The ideal treatment option should be individualized according to the patient's condition and characteristics of injury. According to our study we suggest that cases of acute blunt laryngotracheal trauma patients should be managed following the protocol as mentioned in our study, and we strongly emphasize that Montgomery T-tube should be left for at least 1 complete year in the airway as it results in negligible chances of post-traumatic stenosis of airway later.
Resumo Introdução O tubo T de Montgomery é um dispositivo usado como stent traqueal combinado com tubo de traqueostomia para evitar estenose traqueal pós-operatória. Objetivo Avaliar o resultado do procedimento cirúrgico feito para lesões no pescoço e nas vias aéreas em pacientes com trauma laringotraqueal contuso agudo e o resultado da colocação do tubo T de Montgomery nesses pacientes por 12 anos. Método Entre 2005 e 2017, 19 pacientes com trauma laringotraqueal contuso agudo foram submetidos ao implante do tubo T de Montgomery. Todos os 19 pacientes com trauma laringotraqueal foram submetidos a uma traqueostomia pré-operatória no pronto-socorro por um cirurgião otorrinolaringologista. O implante do tubo T de Montgomery foi feito posteriormente através de uma abordagem externa. O período de seguimento variou de dois a 10 anos. O tubo T de Montgomery foi removido após um período que variou de seis meses a um ano e meio. Resultados A maioria dos pacientes do estudo estava na faixa de 21 a 30 anos. A traqueostomia pré-operatória foi feita em todos os 19 pacientes. Todos, exceto três, tiveram decanulação bem-sucedida e resultado satisfatório em longo prazo. Conclusão O tratamento do trauma laringotraqueal contuso agudo é um desafio que exige uma abordagem multidisciplinar. A opção de tratamento ideal deve ser individualizada de acordo com a condição do paciente e as características da lesão. De acordo com nosso estudo, sugerimos que os casos de pacientes com trauma laringotraqueal contuso agudo sejam tratados de acordo com o protocolo mencionado em nosso estudo e enfatizamos fortemente que o implante do tubo T de Montgomery deve ser mantido por pelo menos um ano completo nas vias aéreas, pois resulta em chances insignificantes de posterior estenose pós-traumática das vias aéreas.
RESUMO
Justification: Global developmental delay (GDD) is a relatively common neurodevelopmental disorder; however, paucity of published literature and absence of uniform guidelines increases the complexity of clinical management of this condition. Hence, there is a need of practical guidelines for the pediatrician on the diagnosis and management of GDD, summarizing the available evidence, and filling in the gaps in existing knowledge and practices. Process: Seven subcommittees of subject experts comprising of writing and expert group from among members of Indian Academy of Pediatrics (IAP) and its chapters of Neurology, Neurodevelopment Pediatrics and Growth Development and Behavioral Pediatrics were constituted, who reviewed literature, developed key questions and prepared the first draft on guidelines after multiple rounds of discussion. The guidelines were then discussed by the whole group in an online meeting. The points of contention were discussed and a general consensus was arrived at, after which final guidelines were drafted by the writing group and approved by all contributors. The guidelines were then approved by the Executive Board of IAP. Guidelines: GDD is defined as significant delay (at least 2 standard deviations below the mean with standardized developmental tests) in at least two developmental domains in children under 5 years of age; however, children whose delay can be explained primarily by motor issues or severe uncorrected visual/ hearing impairment are excluded. Severity of GDD can be classified as mild, moderate, severe and profound on adaptive functioning. For all children, in addition to routine surveillance, developmental screening using standardized tools should be done at 9-12 months,18-24 months, and at school entry; whereas, for high risk infants, it should be done 6-monthly till 24 months and yearly till 5 years of age; in addition to once at school entry. All children, especially those diagnosed with GDD, should be screened for ASD at 18-24 months, and if screen negative, again at 3 years of age. It is recommended that investigations should always follow a careful history and examination to plan targeted testing and, vision and hearing screening should be done in all cases prior to standardized tests of development. Neuroimaging, preferably magnetic resonance imaging of the brain, should be obtained when specific clinical indicators are present. Biochemical and metabolic investigations should be targeted towards identifying treatable conditions and genetic tests are recommended in presence of clinical suspicion of a genetic syndrome and/or in the absence of a clear etiology. Multidisciplinary intervention should be initiated soon after the delay is recognized even before a formal diagnosis is made, and early intervention for high risk infants should start in the nursery with developmentally supportive care. Detailed structured counselling of family regarding the diagnosis, etiology, comorbidities, investigations, management, prognosis and follow-up is recommended. Regular targeted follow-up should be done, preferably in consultation with a team of experts led by a developmental pediatrician/ pediatric neurologist.
RESUMO
Background & objectives: Atypical El Tor strains of Vibrio cholerae are frequently implicated in outbreaks of cholera. It is important to understand genetic variations of such strains which impact clinical and epidemiological outcomes. The present study was carried out to characterize an outbreak of cholera which occurred between July 8 and 13, 2018, in a remote settlement in Nashik district, Maharashtra. Methods: A large number of acute diarrhoea cases were reported in Rahude village, Nashik, Maharashtra since July 8, 2018. Molecular characterization of the isolated strains of V. cholerae was done. Results: 195 cases of cholera were detected from a population of 850 (attack rate 22.9%) with two deaths (Case Fatality Ratio of 1.03). A non-haemolytic polymyxin B sensitive strain of V. cholerae O1 Ogawa was isolated from 5/14 fecal samples. Molecular characterization of the isolates indicated that this strain was an altered El Tor (AET) strain. Deletion of the trinucleotide ‘GTA’ in the rstB gene, a unique feature of classical strains, was observed. Interpretation & conclusions: A cholera outbreak caused by a non-haemolytic polymixin B sensitive AET strain, occurred from July 8 to 13, 2018, in a remote settlement in western India. The molecular characterization of the outbreak strains highlighted an assortment of genetic determinants, stressing the need to monitor the genetic attributes of V. cholerae O1 in outbreaks for better understanding and mapping of clinical and epidemiological changes.
RESUMO
Animal models are useful in glaucoma research to study tissue response to wound healing. Smaller animals such as rats offer additional advantages in terms of availability of detection antibodies and microarrays with cheaper maintenance costs. In this study, we describe a glaucoma filtering surgery (GFS) model in adult Sprague–Dawley rats by performing a sclerostomy using a 26?G needle and additionally placing a silicone tube (27 G) connecting the anterior chamber to the subconjunctival space to maintain a patent fistula for the flow of aqueous humor, thus providing a more definitive bleb. This technique will be useful in identifying and modifying newer targets in the wound healing process in order to improve surgical outcomes following GFS
RESUMO
BACKGROUND Implementation of the exit examination for medical graduates in India has been debated for many years. The national exit test (NEXT), under the construct of the National Medical Commission Act, would serve two purposes: first, it will be a common exit/licentiate examination for all Indian medical graduates, and second, it will be a test for postgraduate selections for all specialties. There has been no research or evidence on stakeholders’ opinion on this test. We aimed to assess the perspective of medical faculties, nationwide, regarding the implementation of NEXT. METHODS We conducted a nationwide, cross-sectional, questionnaire-based pilot survey. The Google survey form with close- and open-ended questions was forwarded via email and WhatsApp to various groups. RESULTS Two hundred and forty-five medical teachers participated, of which 35.9% were from Gujarat, 44.9% were working in government colleges, 91.43% had MD/MS as the highest professional degree, 50% had >15 years of experience and were from different medical specialties. The majority felt that the NEXT examination was a positive step, 82.5% suggested that a national selection/testing authority should conduct it, 36.3% suggested having the test after internship while 32.7% expected some weightage for each year of the medical programme, and 84.1% agreed that all the learning domains should be assessed by various strategies. DISCUSSION Faculties welcomed the NEXT examination under a national testing authority. The necessity of this examination is to have uniform standards and quality for medical graduates irrespective of their institutes. Assessment of all the domains will make the Indian medical graduate more competent for the job or residency programmes.
RESUMO
Abstract A simple, precise, accurate and robust high performance liquid chromatographic method has been developed for simultaneous estimation of Torsemide and Eplerenone in tablet dosage form. Design of experiment was applied for multivariate optimization of the experimental conditions of RP-HPLC method. A Central composite design was used to study the response surface methodology and to analyse in detail the effects of these independent factors on responses. Total eleven experiments along with 3 center points were performed. Two factors were selected to design the matrix, one factor is variation in ratio of Acetonitrile and the second factor is flow rate (mL/min). Optimization in chromatographic conditions was achieved by applying Central composite design. The optimized and predicted data from contour diagram comprised mobile phase (acetonitrile, water and methanol in the ratio of 50: 30: 20 v/v/v respectively), at a flow rate of 1.0 ml/min and at ambient column temperature. Using these optimum conditions baseline separation of both drugs with good resolution and run time of less than 5 minutes were achieved. The optimized assay conditions were validated as per the ICH guidelines (2005). Hence, the results showed that the Quality by design approach could successfully optimize RP-HPLC method for simultaneous estimation of Torsemide and Eplerenone.

RESUMO
Purpose@#Papillary thyroid cancer (PTC) has a high incidence of BRAF V600E mutation. The purpose of this study was to evaluate the potential relationship between thyroiditis and BRAF V600E mutation status in patients with PTC. We investigated how a selective inhibitor of BRAF V600E PLX4032 affects the proliferation and inflammatory cytokine levels of thyroid cancer. @*Methods@#Two thyroid cancer cell lines TPC1 and 8505C were treated with PLX4032, an analysis was done on cell growth, cell cycle, the degree of apoptosis, and levels of inflammatory cytokines. To identify the functional links of BRAF, we used the STRING database. @*Results@#Docking results illustrated PLX4032 blocked the kinase activity by exclusively binding on the serine/threonine kinase domain. STRING results indicated BRAF is functionally linked to mitogen-activated protein kinase. Both cell lines showed a dose-dependent reduction in growth rate but had a different half maximal inhibitory concentration value for PLX4032. The reaction to PLX4032 was more sensitive in the 8505C cells than in the TPC1 cells. PLX4032 induced a G2/ M phase arrest in the TPC1 cells and G0/G1 in the 8505C cells. PLX4032 induced apoptosis only in the 8505C cells. With PLX4032, the TPC1 cells showed decreased levels of vascular endothelial growth factor, granulocyte-macrophage colonystimulating factor, chemokine (C-C motif) ligand 2/monocyte chemoattractant protein 1, whereas the 8505C cells showed significantly decreased levels of IL-8, serpin E1/plasminogen activator inhibitor-1, and matrix metalloproteinase (MMP)-3. @*Conclusion@#PLX4032 was cytotoxic in both TPC1 and 8505C cells and induced apoptosis. In the 8505C cells, inflammatory cytokines such as IL-8 and MMP-3 were down-regulated. These findings suggest the possibility that the BRAF V600E mutation needs to target inflammatory signaling pathways in the treatment of thyroid cancer.
RESUMO
Background: The present study was conducted with the objective to assess the spectrum of liver disease in pregnancy, and its course and effect on maternal and fetal outcomes.Methods: The present study was conducted as a prospective follow up study in the department of Obstetrics and Gynaecology, J. K. Hospital for a period of 1 year. The pregnant women between the ages of 18-35 years presenting with symptoms suggestive of underlying liver disease were selected. Socio demographic details and clinical history was obtained from all the participants and they were subjected to liver function test (LFT). All patients were followed till 2 weeks post-partum period. The maternal and fetal outcomes were noted.Results: The following results were obtained: pregnancy-induced hypertension (PIH) was the most common cause of abnormal LFT (46.66%), about 57.5% patients delivered at term, 63.3% patients delivered vaginally, mostly cases delivered a term healthy neonate between 2.5-3.0 kg weight with Apgar score >7 at 5 minutes after birth and maternal complications were seen in 10.82% cases.Conclusions: Our study shows that though liver disease is uncommon in Indian pregnant women, but it is associated with high maternal and perinatal morbidity. A high index of suspicion of liver disease, early diagnosis, prompt referral to a higher centre when required, appropriate supportive management, and a proactive policy of early delivery when indicated may improve the maternal and fetal outcomes in pregnant women with liver disease. Thus LFT should be conducted as a routine investigation in all pregnant females during first and second trimester.
RESUMO
Spine is an unusual site for giant cell tumour (GCT). The largest of the series was published by Dahlin in the year 1977. Giant cell tumour of the spine is most aggressive benign tumour of the spine with unpredictable outcome. We report a case of 29 years old male patient with giant cell tumour of spine, clinically diagnosed as spinal tuberculosis. Patient presented with cord compression and neurological deficits in upper limb. Patient presented with clinical as well as radiological instability.Giant cell tumour (GCT) of bone is a rare neoplasm that accounts for approximately 5 % of all primary bone tumours in adults.1 GCT most frequently occurs at the end of long bones.2 Giant cell tumour also occurs in the mobile spine, but this location accounts for only 2 - 4 % of cases.3 In all locations, the neoplasm occurs most commonly between the ages of 20 - 45 years and it affects males and females with equal frequency.1 It is the most aggressive of the benign primary tumours of the spine,4 with a high predilection for recurrence. Due to the unusual site and nonspecific symptoms Giant cell tumour of spine is a challenge to the treating surgeons. We report a case of giant cell tumour cervical vertebrae where in patient presented with signs and symptoms of cord compression and was provisionally diagnosed as tuberculosis spine.
RESUMO
Ovarian torsion results from twisting of the ovary about the suspensory ligament, which contains the ovarian artery and vein, lymphatic’s, and nerves. Volvulus is a torsion of a segment of the alimentary tract, that often leads to intestinal obstruction. Ovarian torsion leading to sigmoid volvulus is the rarest complication which authors found in this case. Hence the case was presented. A 28-year-old women presented with acute pain in abdomen since 14 hours, followed by 2 episodes of vomiting, abdominal distension since 10 hours. Plain X-ray Abdomen erect was done which showed ‘Coffee bean’ sign with multiple air fluid levels suggestive of sigmoid volvulus. On laparotomy, after opening the peritoneum, large right ovarian cyst around 12×11×10 cm with solid and haemorrhagic content with long pedicle around 8 cm with 3 turns of torsion was noted. Abutting the ovarian mass, sigmoid colon was seen twisted around its mesentery including the twisted ovarian pedicle. Hence, the twisted component included the twisted ovarian pedicle and twisted sigmoid mesentery. Stepwise detorsion of ovarian pedicle followed by oophorectomy was done. For sigmoid volvulus, resection of vascular compromised sigmoid colon and descending colon stoma was done. Reanastomosis was done later after 3 months post operatively.
RESUMO
The present study was aimed to know the pulmonary toxicity by individual toxicities of cadmium, chlorpyrifos and their combination in albino wistar rats. The experiment was carried out for 28 days. Group 1 - Control. Group 2 - Cadmium chloride (Cd) @ 22.5 mg/ kg b.wt /per oral / day. Group 3 - Chlorpyrifos (CPF) @ 25 mg/ kg b.wt /per oral / day. Group 4 - Cadmium chloride (Cd) @22.5 mg + Chlorpyrifos (CPF) @ 25 mg/ kg b.wt /per oral / day. Lungs showed mild to moderate congestion in groups 2 and 3 and moderate to severe in group 4 on 15th and 29th day of the experiment. Lung sections of control rats showed normal architecture. Lung sections of group 2 rats on 15th day showed hemorrhages in the interstitium spaces with infiltration of lymphocytes, On 29th day, mild hyperplasia and desquamated bronchial epithelial cells, peri bronchial and peri vascular lymphoid aggregates were noticed. The sections of lung on 15th day of group 3 rats showed exudate and desquamated epithelial cells in the lumen of secondary bronchiole , on 29th day, emphysematous alveoli with loss of architecture of alveolar epithelium, interstitial edema with infiltration of lymphocytes, mild hyperplasia of bronchial epithelial cells were also noticed. In group 4 rats, similar lesions as described in groups 2 and 3 were observed with severe intensity on 15th and on 29th day of the experiment. In combined toxicity group, the severity of lesions were more thus suggesting synergistic effects of these components.
