Abstract
The present study was undertaken with an objective to frame out the lipid profile of Indian Women Boxers. Women boxing is a newly recognized game and no work has been reported on elite female boxers in India till date. The study was based on a sample of 45 women boxers (age 17 ~ 24 years) attending Senior National Women Boxing Camp at Sports Authority of India. Each subject was evaluated for Lipid Profile variables at the beginning and end of the six weeks training camp. Fasting blood samples were taken from the antecubital vein by venipuncture. Before the samples drawn the subjects were asked to take rest for ten minutes. The blood sample was analyzed by HITACHI UV-2000 spectrophotometer (Japan). Standard techniques and procedures were followed for all the estimation. Volume and intensity of different components of training was measured by observational and physiological methods. Data were subjected to statistical treatment like mean and standard deviation. Test of significance't' - test (for paired sample) was applied to asses the difference in pre & post-test. Results reveal that mean (+/-SD) Cholesterol, Triglyceride, LDL, HDL - Cholesterol and Cholesterol / HDL Cholesterol ratio was 144.7 +/- 3.6 mg%, 59.7 +/- 17.5 mg% 81.4 +/- 21.1 mg% 51.3 +/- 8.2 mg% and 2.8 +/- 0.5 respectively as found in the pre-test. Significant difference (P < 0.01) was observed in Cholesterol, LDL-Cholesterol, HDL Cholesterol level in the post-test. The study concludes that women who practice sport of boxing on regular basis have a favorable lipid profile. A significant change in lipid profile of the boxers was observed after 6 weeks' training program.

Abstract
Central neurocytomas are benign neuronal tumours generally found in the lateral or third ventricles. They are rare, comprising < 1% of all brain tumours. It is frequently confused with other tumours of the central nervous system particularly oligodendroglioma. The present study was done to analyse the histopathological features including immunohistochemical profile of these rare tumours. Eight cases were taken up for the study. Seven of the cases had an intraventricular location and one was located outside the ventricles. Increased intracranial pressure was the most common presenting symptom. Microscopically all tumours were composed of small uniform cells with perinuclear halos and regular round nuclei. The tumour in extraventricular location showed atypical features. Immunohistochemistry showed positivity for neuronal markers. The present series highlights the characteristic clinical and pathological findings of this rare brain tumour. Immunostaining for neuronal markers are essential for distinguishing them from other small round cell tumours of the brain.

Abstract
OBJECTIVES Women boxing have got recognition recently and so far no work has been reported on energy expenditure of national women boxers in India. This study was aimed to estimate the energy expenditure in Indian female boxers during sparring. METHODS A total of 20 female boxers were subjected. Energy expenditure was estimated using the same individual's HR-VO2 regression equation. Heart rate was recorded through radiotelemetry. RESULTS Results reveal that average and maximum energy expenditure considering the total duration of boxing are 12.7 +/- 1.3 and 14.4 +/- 1.6 kcal/min. CONCLUSIONS It is concluded that depending on the severity of energy expenditure female boxing comes under heavy category and as it is a pioneer attempt in India, further studies in this aspect are really required which will guide the coaches regarding the energy expenditure pattern in women boxing.

Abstract
We present a case of a 29-year-old woman with known Type 1 diabetes who presented with diabetic ketoacidosis (DKA). Despite appropriate treatment and initial improvement, 12 h after initiation of treatment she deteriorated rapidly and developed pulmonary oedema, cerebral oedema and multiple infarctions of the brain and cervical spinal cord. This resulted in spastic quadraparesis and she has remained wheelchair-bound. These complications of DKA are rare and unpredictable. In this case report we discuss the proposed aetiologies of these complications with reference to our case report and highlight the importance of vigilance for early signs of these complications during the treatment of all patients with DKA.

Abstract
BACKGROUND Demyelinating diseases can present as space occupying lesions with in the brain. It is clinically and radiologically difficult to differentiate them from primary neoplasms. Histopathologically they mimic astrocytic neoplasms closely and identifying these lesions correctly has a profound impact in treatment and prognosis of these patients. AIMS AND OBJECTIVES The objective was to determine the histopathologic features of such acute focal demyelinating disease that clinically presented as brain tumors. MATERIAL AND METHODS Seven cases were included for the study. Detailed histopathological examination including stains for myelin and axon were performed. The histopathological keys in arriving at the right diagnoses included a well demarcated lesion that contains uniform distribution of foamy macrophages in the absence of any associated coagulative necrosis, sheets of gemistocytic astrocytes in the white matter that show well-formed processes, perivascular chronic inflammatory cell infiltration and total absence of myelin with relative preservation of axons within these areas. CONCLUSION The degree of suspicion (clinical, radiological and histopathological) should be high to diagnose these group of lesions. The above-mentioned diagnostic keys should help in arriving at the correct histopathological diagnoses of such cases.

Abstract
AIMS The aims of this study were first, to investigate the relationship between simple anthropometric measures of obesity with visceral fat as assessed by a single slice magnetic resonance imaging (MRI)-scan in patients attending a hospital clinic. Second, to determine which anthropometric measure best relates to the adverse metabolic profile of the metabolic syndrome. METHODS Forty-one male subjects [body mass index (BMI): 30.2 + 5.8 kg/m(2), age: 50.3 + 13.6 years] were studied by MRI-scan to measure visceral fat at L4/L5 level and to investigate its relationship with simple anthropometric measures. Second, we studied 83 male subjects to determine which anthropometric measure best predicts the metabolic complications (using the ATPIII criteria) of obesity in the setting of a hospital clinic. RESULTS Waist circumference was the best anthropometric measurement that correlated with MRI-visceral fat mass assessed at L4/L5 in 41 subjects who had an MRI scan (P = 0.0001, r(2) = 0.36, beta = 0.56) amongst variables which also included age, BMI, sagittal diameter, diabetes and ethnicity. Stepwise multiple regression analysis showed sagittal diameter (P = 0.001, r(2) = 0.4, beta = 0.406), age (P = 0.003, beta = 0.271) and waist circumference (P = 0.012, beta = 0.297) were the best predictors of the adverse metabolic profile of the metabolic syndrome in all 83 male subjects amongst BMI, waist-hip ratio (WHR), ethnicity and diabetes-related factors. CONCLUSIONS Waist circumference is a simple anthropometric parameter that best correlates with single slice MRI-scan, but sagittal diameter (measured using abdominal calipers) better predicts the adverse metabolic profile of the metabolic syndrome. Although there is considerable variation in abdominal fat topography between ethnic groups, and also within populations, sagittal diameter assessment is a technique that is simple and best predicts the metabolic syndrome.

Abstract
Semen samples of fertile and infertile men were analysed by gas liquid chromatography (GLC) for the presence of dichlorodiphenyltrichloroethane (DDT) and its metabolites (1,1-dichloro-2,2-bis(p-chlorophenyl) ethylene) (pp'-DDE); (1,1,1-trichloro-2,2-bis(p-chlorophenyl ethane) (pp'-DDT); (1,1-dichloro-2,2 bis(p-chlorophenyl) ethane) (pp'-DDD); (1,1,1-trichloro-2-(o-chlorophenyl)-2-(p-chlorophenyl) ethane) (op'-DDT), hexachlorocyclohexane (HCH) and its isomers alpha (alpha), beta (beta), gamma (gamma), delta (delta) and aldrin. The biochemical analysis of seminal vesicle and prostatic marker was done by spectrophotometer. The concentrations of alpha-, beta-, gamma-HCH, pp'-DDE and pp'-DDD were higher in the semen of infertile than in that of fertile men. An elevation in the fructose level along with decrease in the gamma-glutamyl transpeptidase and acid phosphatase activity was noticed in infertile men as compared to fertile subjects. The data showed correlation between alpha-, beta-, gamma-HCH, pp'-DDE, pp'-DDD and seminal vesicle marker fructose and prostatic marker gamma-gluatamyl transpeptidase and acid phosphatase in infertile men. The study suggests that the chlorinated pesticides may influence the semen quality by affecting the seminal and prostatic functions in infertile men.

Abstract
Radiation-induced brain disorders (RIBD) are uncommon and they are grave sequelae of conventional radiotherapy. In the present report, we describe the clinical spectrum of RIBD in 11 patients who received post-surgery conventional megavoltage irradiation for residual pituitary tumours. Of these 11 patients (nine men, two women), seven had been treated for non-functioning pituitary tumours and four for somatotropinomas. At the time of irradiation the age of these patients ranged from 30 to 59 years (mean, 39.4 +/- 8.3; median, 36) with a follow-up period of 6-96 months (mean, 18.3 +/- 26.4; median, 11). The dose of radiation ranged from 45 to 90 Gy (mean, 51.3 +/- 13.4; median, 45), which was given in 15-30 fractions (mean, 18.6 +/- 5.0; median, 15) with 2.8 +/- 0.3 Gy (median, 3) per fraction. The biological effective dose calculated for late complications in these patients ranged from 78.7 to 180 Gy (mean, 99.1 +/- 27.5; median, 90). The lag time between tumour irradiation and the onset of symptoms ranged from 6 to 168 months (mean, 46.3 +/- 57.0; median, 57). The clinical spectrum of RIBD included new-onset visual abnormalities in five, cerebral radionecrosis in the form of altered sensorium in four, generalized seizures in four, cognitive dysfunction in five, dementia in three and motor deficits in two patients. Magnetic resonance imaging (MRI)/CT of the brain was suggestive of radionecrosis in eight, cerebral oedema in three, cerebral atrophy in two and second neoplasia in one patient. Associated hormone deficiencies at presentation were hypogonadism in eight, hypoadrenalism in six, hypothyroidism in four and diabetes insipidus in one patient. Autopsy in two patients showed primitive neuroectodermal tumour (PNET) and brainstem radionecrosis in one, and a cystic lesion in the left frontal lobe following radionecrosis in the other. We conclude that RIBD have distinctive but varying clinical and radiological presentations. Diabetes insipidus and PNET as a second neoplastic disorder in adults following pituitary irradiation have not been reported previously.

Abstract
Glucocorticoids play an important role in the pathogenesis of obesity and insulin resistance. Impaired conversion of cortisone (E) to cortisol (F) by the type 1 isoenzyme of 11beta-hydroxysteroid dehydrogenase (11beta-HSD) in obesity may represent a protective mechanism preventing ongoing weight gain and glucose intolerance. We have studied glucocorticoid metabolism in 33 male subjects with type 2 diabetes mellitus [age, 44.2 +/- 13 yr; body mass index (BMI), 31.1 +/- 7.5 kg/m(2) (mean +/- sd)] and 38 normal controls (age, 41.4 +/- 14 yr; BMI, 38.2 +/- 12.8 kg/m(2)). Circulating F:E ratios were elevated in the diabetic group and correlated with serum cholesterol and homeostasis model assessment-S. There was no difference in 11beta-HSD1 activity between diabetic subjects and controls. In addition, 11beta-HSD1 activity was unaffected by BMI in diabetic subjects. However, in control subjects, increasing BMI was associated with a reduction in the urinary tetrahydrocortisol+5alpha-tetrahydrocortisol:tetrahydrocortisone ratio (P < 0.05) indicative of impaired 11beta-HSD1 activity. The degree of inhibition correlated tightly with visceral fat mass. Changes in 11beta-HSD1 activity could not be explained by circulating levels of adipocytokines. Impaired E to F metabolism in obesity may help preserve insulin sensitivity and prevent diabetes mellitus. Failure to down-regulate 11beta-HSD1 activity in patients with diabetes may potentiate dyslipidemia, insulin resistance, and obesity. Inhibition of 11beta-HSD1 may therefore represent a therapeutic strategy in patients with type 2 diabetes mellitus and obesity.

Abstract
James Brailsford went from humble beginnings to become an eminent radiologist through his ability, determination and immense diligence. He made a late start in medicine but became one of the world's leading authorities on skeletal diseases; he wrote the classic textbook The Radiology of Bones and Joints and described the eponymous Morquio-Brailsford syndrome. In 1934 he was elected first President of the British Association of Radiologists, of which he was founder. This later became the Faculty of Radiologists at the Royal College of Surgeons and is now the Royal College of Radiologists.

Abstract
We describe four classical cases of familial hemophagocytic lymphohistiocytosis (FHL), a macrophage-related, autosomal recessive fatal disorder. Parental consanguinity was present in three cases. All patients presented with fever, neurological involvement of varying degrees, hepatosplenomegaly, cytopenias, deranged liver function tests, and coagulogram, hypofibrinogenemia (three cases), and hyperlipidemia (one case). An antemortem diagnosis could not be made, although it was suspected in one case. Necropsy (done in three cases and postmortem liver biopsy in one case) revealed classical features of FHL. Florid lymphohistiocytic infiltrate exhibiting hemophagocytosis was seen in the bone marrow, liver, spleen, lymph nodes and brain (examined in two case). In addition to this, focal infiltrates were seen in the kidneys, lung, pancreas, testes, adrenals, and skin. Marked lymphoid depletion was seen in one case in the lymph nodes and spleen.

Abstract
Subependymomas are highly differentiated slow growing gliomas. They are one of the few gliomas which are biologically benign. They are extremely rare in children. However, after going through the histopathology records of our department of fourteen years (1983-1997) we found that five (20%) cases of subependymomas have been diagnosed in children out of a total of twenty-six subependymomas. Two of our cases showed the presence of osseous metaplasia, a hitherto undescribed finding.

Abstract
The objective of this study was to investigate the correlation between lead and cadmium with seminal vesicle and prostatic markers. Semen samples categorized into fertile and infertile were evaluated for the presence of lead and cadmium and biochemical markers in the seminal plasma. Associations between lead and fructose, acid phosphatase and gamma-glutamyl transpeptidase (gamma-GT) were observed. However, no such relationships were noticed for cadmium. It is concluded that lead may be one of the pollutants indirectly affecting semen quality by altering the functions of accessory sex glands.

Abstract
BACKGROUND Common variable immune deficiency (CVID) is prone to under-diagnosis and may not reach relevant specialists until late in life. Morbidity is most commonly due to acute-on-chronic respiratory infections leading to respiratory failure. AIM To investigate respiratory complications, lung function and high-resolution computerized tomography scan (HRCT) findings and mortality in 47 patients with CVID. SETTING A regional immunology unit (Birmingham Heartlands Hospital). DESIGN Retrospective observational case-note study following the introduction of shared care between immunology and respiratory medicine. RESULTS Age at diagnosis ranged from 5 to 72 years, with a median time from development of first symptoms to diagnosis of 4.0 years. There was delay in referral between chest physicians and immunologists, (median referral time between specialities >5 years). Forty-two patients had respiratory complications, due to bronchiectasis (n=32), asthma (n=7), recurrent chest infections (n=9) without concomitant evidence of structural lung damage, and granulomatous lung disease (n=2). Spirometry was abnormal in 10/39 patients (7 obstructive, 3 restrictive). Bronchiectasis was confirmed on chest radiograph (n=9) and HRCT (n=24). Despite the high prevalence of bronchiectasis, few patients had received instruction in physiotherapy and sputum culture results were sparse. DISCUSSION To reduce the morbidity associated with CVID, there needs to be greater awareness of respiratory complications, particularly amongst physicians caring for such patients. Emphasis has been placed on adequate dosage of immunoglobulin, but early involvement by a respiratory physician is essential to monitor lung function and initiate optimal therapy, to minimize the occurrence and progression of lung damage.

Abstract
Rabies is a communicable disease and a significant health hazard. Histopathological confirmation of the diagnosis depends on the demonstration of Negri bodies - characteristic intracytoplasmic inclusions. In cases where these are not seen, immunohistochemistry serves as a useful adjunct. After its establishment in the central nervous system, the rabies virus is known to reach peripheral organs by a centrifugal spread. The present study was undertaken with the aim of demonstrating rabies viral antigen (RVAg) in the extracranial organs. Eleven confirmed cases of rabies were analysed and RVAg was found in the adrenal glands, heart, gastrointestinal tract and pancreas, confirming the centrifugal spread of the virus. The detection of RVAg in the extracranial sites may serve as a useful tool in the ante-mortem diagnosis by subjecting the extracranial tissue to biopsy and subsequent immunohistochemistry.

Abstract
BACKGROUND Primary central nervous system lymphoma (PCNSL) is rare and accounts for 1 to 2% of all lymphomas. There are conflicting reports about the rise in incidence of PCNSL cases in the last two decades; this has largely been attributed to an increase in incidence of AIDS and other immunosuppressive states in some studies. This study was undertaken to view the trend of PCNSL at the Postgraduate Institute of Medical Education and Research, Chandigarh, which is a referral hospital in northern India. METHODS The PCNSL cases from our surgical material of 15 years (1985-1999) were reviewed. Slides were examined independently by three histopathologists. Immunophenotyping was done on paraffin-embedded tissue using indirect immunoperoxidase technique. RESULTS Out of a total of 3,325 intracranial tumors diagnosed during this period (1985-1999), there were 40 cases (1.2%) of PCNSL; gliomas accounted for 1,531 cases (46.04%). The age ranged from 24-75 years with the sex ratio (M:F) being 2:1. HIV serology, available in 14 cases, was negative in all. The parietal lobe was the most common site of involvement. Diffuse large cell lymphoma was the most common morphological type. Immunohistochemistry could be done in 31 cases; 28 cases were found to be B-cell type whereas 3 cases were T-cell type. No statistically significant increase was seen on comparing the number of cases at 5-year intervals. CONCLUSION This study revealed that there has been no significant increase in PCNSL cases over the last 15 years.

Abstract
GISTS are the largest category of non-epithelial neoplasms of stomach and small bowel. Numerous immunohistochemical, ultrastructural and flow cytometry studies have been carried out for evaluation of prognostic factors which could predict malignant behaviour of these neoplasms. Tumor size of 5 cm and mitosis of 2/10 hpf were suggested as two important parameters which could predict the chances of recurrence and clinically aggressive course. The aim of this study is to examine predictive value of these two important parameters in assigning the tumors as high, intermediate and low risk groups. Using these two parameters we categorized 30 cases of GIST over a period of 6 years (1990-95) into low, intermediate and high risk groups and examined other features of these cases. Based on these two parameters alone we found that 4 cases each in low and intermediate group could be assigned to a higher risk group clinically as there were presence of adjacent organ infiltration, lymphatic emboli, serosal nodules, lymph node metastasis and transmural infiltration. Hence, other features like hemorrhage, necrosis and anaplasia should also be included in risk assessment. Metaplastic tissues like bone, cartilage and adipose tissues were seen only in high-risk categories.

Abstract
DNA ploidy and synthetic phase fraction (SPF) of 52 cases of primary intracranial neoplasms have been determined from fresh tissues and the data was correlated with histopathological typing and grading. Fresh tumour tissues from 52 random surgical biopsies (28 malignant and 24 benign) were obtained from neurosurgical operations during the period 1994-1996. The cells were analysed in Becton Dickinson flowcytometer fitted with Consort 30 programme and 'Sober' software. Percentage of diploid cells, proliferative cells and DNA aneuploidy were evaluated. The tumours were classified and graded according to WHO classification (1993). On histology, there were 28 malignant (grade II to IV) and 24 benign cases (grade I). All the histologically benign tumours in this study showed diploid DNA content with the exception of a pituitary adenoma which had a heterogeneous population of cells. The S phase fraction in all the benign cases was less than 10% except in the case of choroid plexus papilloma (S-phase 54%) and an atypical meningioma (S-phase 14%). Out of the 28 malignant tumours, 12 cases were aneuploid (43%) and the rest were diploid (57%). Among the 16 diploid tumours, SPF was more than 10% in eight cases. DNA aneuploidy and high SPF are more common in histologically malignant tumours than benign tumours. SPF is a reflection of proliferation potential of a tumour and may have some role in prognostication of brain tumours.

Abstract
78 autopsy proven cases of infective endocarditis (IE) seen during 1983 to 1995 were retrospectively reviewed. The brain was available for examination in 44 cases. In the remaining cases, brain was not examined because examination of it was not requested due to lack of neurological findings. Brain lesions were observed in 35 out of 44 cases of IE. Assuming remaining 34 cases to be without brain lesions, the brain involvement in IE would be 44.87% (35 out of 78 cases). Mean age of all cases of IE and those with brain lesions was similar i.e. 26.5+/-16.6 years and 26.6+/-13.06 years respectively. Largest number of cases with neuropathological lesions were associated with normal valve IE (48.57%). Mitral valve was most commonly involved in cases with CNS complications (57.14%) (p<0.05). The various types of brain lesions were infarction (68.57%), haemorrhage (57.14%), cerebral micro-abscess (31.42%) and focal meningitis (14.28%). More than one type of lesion was observed in 19 cases, indicating complicated nature of brain lesions in fatal cases of IE. Left sided middle cerebral artery (MCA) territory was the commonest site of infarction and haemorrhage. Staphylococcus aureus appeared to be the most common organism in fatal cases of IE. Normal valve IE with or without CNS complications constitutes a significant group in India and is different from the west as far as the predisposing conditions are concerned.

Abstract
Human parainfluenza virus type 3 (HPIV3) is one of the major causes of bronchiolitis, pneumonia, and croup in newborns and infants. Cellular immunity involving major histocompatibility complex (MHC) class I and class II molecules plays an important role in controlling virus infection. Several viruses have been shown to down-regulate gamma interferon (IFN-gamma)-mediated MHC class II expression. In this communication, we show that HPIV3 strongly inhibits the IFN-gamma-induced MHC class II expression in HT1080 human fibrosarcoma cells. The culture supernatant of HPIV3-infected cells also inhibited IFN-gamma-induced MHC class II expression, a phenomenon that was found to be due, in large part, to alpha/beta interferon (IFN-alpha/beta). Expression of MHC class I and intercellular adhesion molecule 1 occurred efficiently in cells simultaneously infected with HPIV3 and treated with IFN-gamma, indicating that the inhibitory effect of HPIV3 was specific to MHC class II. STAT1 activation was not affected by HPIV3 at early postinfection times but was partially inhibited at later times. These data suggested that the potent inhibition of MHC class II expression was, in major part, due to a defect downstream of STAT1 activation in the IFN-gamma-induced MHC class II expression pathway. Class II transactivator (CIITA) is the unique mediator of IFN-gamma-induced transcription from the MHC class II promoter. By RNase protection analysis, CIITA expression was found to be strongly inhibited in HPIV3-infected cells. The culture supernatant containing IFN-alpha/beta, on the other hand, inhibited MHC class II expression without affecting STAT1 and CIITA expression. These data indicate that HPIV3 inhibits IFN-gamma-induced MHC class II expression primarily by the viral gene products targeting CIITA and additionally by inducing IFN-alpha/beta to target one or more steps further downstream.

Abstract
Human parainfluenza virus type 3 (HPIV-3) is an airborne pathogen that infects the epithelial cells of the respiratory tract. In the present study we investigated the interaction of HPIV-3 with the type II alveolar human lung polarized epithelial A549 cells. Although HPIV-3 entry and budding were bidirectional from both the apical and the basolateral domains, HPIV-3 exhibited preferential entry and release from the apical pole. While disruption of the cellular actin microfilament and microtubule by cytochalasin D and nocodazole, respectively, had no effect on virus entry, disruption of the microtubule but not the microfilament inhibited HPIV-3 release.

Abstract
OBJECTIVE In a retrospective study we reported absence of abdominal pain in 35% of elderly patients with peptic ulcer disease. We now report a prospective study on this question. METHODS Patients undergoing upper GI endoscopy were systematically questioned before endoscopy. A reproducible method for identifying the location of symptoms was used. Among patients referred for upper endoscopy, there was no selection of patients for study purposes as all had strong indications, such as pain, dyspepsia, GI bleeding, weight loss, or anemia. Patients were divided into two groups according to age: A younger group consisting of patients <50 yr (mean, 33.6 yr) and an older group >60 yr (mean, 70.9 yr). RESULTS A total of 277 patients were included in the study. There was no significant difference in reported use of medications, alcohol, or cigarette use between the groups. Of the 106 patients with peptic ulcer, 15 (14.2%) had not experienced pain. Abdominal pain was absent in 5 (6.9%) of the younger patients and 10 (29.4%) of the older patients. The difference was significant using the chi2 method (p = 0.004). A trend toward an even higher proportion of pain-free peptic ulcer disease was noted in the elderly female group (37.5%), but it did not reach statistical significance. CONCLUSIONS Absence of abdominal pain is confirmed in approximately 30% of elderly patients with peptic ulcer disease.

Abstract
Rabies is a communicable disease that is almost always fatal. In its classic form, rabies is well recognized, but cases presenting with a paralytic illness mimic Landre's Guillain-Barre syndrome and in such cases the diagnosis remains in doubt. This problem is further compounded when the history of dogbite is not forthcoming. At autopsy rabies can be diagnosed by subjecting fresh tissue to virologic investigations or examining formalin-fixed paraffin-embedded tissue sections for the presence of characteristic inclusions; that is, the Negri bodies. However, these inclusions are not present in all cases. Hence, the need arises for a better method for diagnosis. The present study utilized immunohistochemistry as a diagnostic tool using both monoclonal and polyclonal antirabies antibodies in 20 cases of rabies encephalomyelitis. The diagnosis of rabies could be confirmed in 17 cases (85%) based on neuropathologic findings alone. In contrast, immunohistochemistry yielded positive results in all cases. Moreover, the amount of rabies viral antigen was much more abundant than could be expected from the histopathologic findings. Thus immunohistochemistry is a rapid, safe, sensitive and specific technique for the diagnosis of rabies.
