Protective effects of Chromolaena odorata extract on experimental benign prostatic hyperplasia in rats.

Benign prostatic hyperplasia (BPH) is an age-related disease in dogs and man leading to prostate enlargement which impinges on the urethra causing urinary outflow obstruction. Due to the side effects of surgery and chemotherapy used for the treatment of this disease, attention is now focused on phytotherapeutics for its management. Thus, we investigated the inhibitory effect of hydro-methanol extract of Chromolaena odorata (HMECO) on testosterone propionate (TP)-induced BPH rat model. A total of forty-two 10-12 weeks old male Sprague-Dawley outbred albino rats (Rattus norvegicus) weighing 200 - 250 g were randomly divided into six equal groups of seven rats each based on body weight as follows: A) Control group given phosphate-buffered saline orally and corn oil subcutaneously (SC) once daily, B) TP at a dose of 3.00 mg kg-1 SC once daily, C) TP at a dose of 3.00 mg kg-1 SC and finasteride at a dose of 10.00 mg kg-1 orally once daily, D) TP at a dose of 3.00 mg kg-1 SC plus 200 mg kg-1 HMECO orally once daily, E) TP at a dose of 3.00 mg kg-1 SC plus 400 mg kg-1 HMECO orally once daily and F) TP at a dose of 3.00 mg kg-1 SC plus 800 mg kg-1 HMECO orally once daily for 28 days. Results showed that HMECO significantly reduced prostate weight, prostatic index; serum levels of testosterone and prostatic epithelial thickness and increased luminal diameter in BPH induced rats. Thus, the results of this study suggest that C. odorata is a potential pharmacological candidate for the management of BPH.

Important Mycoses of Wildlife: Emphasis on Etiology, Epidemiology, Diagnosis, and Pathology-A Review: PART 1.

In the past few years, there has been a spurred tripling in the figures of fungal diseases leading to one of the most alarming rates of extinction ever reported in wild species. Some of these fungal diseases are capable of virulent infections and are now considered emerging diseases due to the extremely high number of cases diagnosed with fungal infections in the last few decades. Most of these mycotic diseases in wildlife are zoonotic, and with the emergence and re-emergence of viral and bacterial zoonotic diseases originating from wildlife, which are causing devastating effects on the human population, it is important to pay attention to these wildlife-borne mycotic diseases with zoonotic capabilities. Several diagnostic techniques such as fungal isolation, gross pathology, histopathology, histochemistry, cytology, immunohistochemistry, radiography, CT, and molecular methods such as PCR or ELISA have been invaluable in the diagnosis of wildlife mycoses. The most important data used in the diagnosis of these wildlife mycoses with a zoonotic potential have been re-emphasized. This will have implications for forestalling future epidemics of these potential zoonotic mycotic diseases originating from wildlife. In conclusion, this review will highlight the etiology, epidemiology, diagnosis, pathogenesis, pathogenicity, pathology, and hematological/serum biochemical findings of five important mycoses found in wild animals.

Important Mycosis of Wildlife: Emphasis on Etiology, Epidemiology, Diagnosis, and Pathology-A Review: PART 2.

Wild animals are an important component of the ecosystem, and play a major role in it. However, in recent years, there has been an astronomical increase in the incidence of wildlife mycotic diseases leading to wildlife extermination. It is important to note that most of these mycotic diseases are zoonotic, and since there is a lot of attention given to zoonosis of a bacterial or viral origin in recent times, it is important to look into the mycotic diseases which may have zoonotic potential. Previously, the authors expatiated on some major wildlife mycotic diseases. In this review, we shed light on the etiology, epidemiology, diagnosis, pathogenesis, pathogenicity, macroscopic and microscopic pathology, and hematological and serum biochemical findings of dermatophytosis, coccidioidomycosis, blastomycosis, and sporotrichosis, which are very important mycoses of wildlife.
