Indian major carp, Cirrhinus cirrhosus was considered to monitor culture and health status in farm condition from Bhaluka and Muktagacha of Mymensingh region of Bangladesh for a period of seven months starting from September, 2010 to March, 2011. Monthly sampling was carried out for growth and health condition. Samples of skin and muscle, gill, liver and kidney were observed by clinical and histological techniques. Water temperature was at unfavorable levels but, dissolved oxygen, pH, alkalinity, ammonia and nitrite of water were within the favorable range for fish culture during the months of December and January. Clinically weak body, rough skin, scale loss, thick gill filaments, ulcer and gray brownish color were observed. Among the affected fish organs like skin, muscle and gill were found to be more affected than those of the internal organs, liver and kidney. Major pathologies in the skin and muscle were loss of epidermis and dermis, presence of fungal granuloma, fungal hyphae, necrosis, hemorrhages, vacuums and melanocytes. Protozoan cysts, clubbing, hemorrhages, necrosis and hypertrophy were found in the gill. Necrosis, hemorrhage, pyknosis and vacuums were observed in liver. Common pathological signs like necrosis, hemorrhage, pyknosis, vacuums and degenerated kidney tubules were noticed in kidney. Overall, in the clinical and histopathological studies fishes were found to be more affected during the colder months i.e., December and January. Whereas, in the month of February the pathological condition of fish gradually started to heal up. In histopathological observation, fishes of Bhaluka farms were more affected than that of Muktagacha fish farms. Epizootic ulcerative syndrome (EUS) and protozoan diseases were noticed in Bhaluka fish farms. DOI: http://dx.doi.org/10.3329/jbau.v11i2.19947 J. Bangladesh Agril. Univ. 11(2): 391-397, 2013

Investigation on health conditions and diseases of juvenile catla (Catla catla) was carried out for clinical and histopathological observations from different farms of Mymensingh region.  A total of eight (8) farms, four Government (Govt.) and four Private (Pvt.) fish farms were selected for the study. The Indian major carp - catla was examined during June, 2010 to May, 2012. Monthly samplings were carried out with 5 fishes from each farm. Altogether 960 fish hosts were examined during the study period. Water quality parameters such as temperature, dissolved oxygen, pH, ammonia, hardness, alkalinity, transparency and depth of water etc. were taken and management practices were investigated fortnightly interval. These were almost similar for all experimental ponds. The risk of being infestation by parasites of catla significantly (p<0.001) increased when the water quality parameters were not maintained the optimum level. Clinical examination of fishes was also carried out for any kind of abnormalities at monthly intervals. For histopathological studies skin, muscle, gill, liver and kidney were collected, processed and stained in Haematoxylin and Eosin. Histologically, catla of different fish farms were more affected in colder months (October to January). Structures of fish organs were normal from March to July. In the months of September, minor pathologies were found to be started and in the months of February the pathological condition of fish gradually reduced. Pathological changes like necrosis, fungal granuloma, protozoan and monogenean cyst, vacuolation, melanomacrophase, haemorrhage, hypertrophy, hyperplasia and clubbing were recorded in all the investigated organs. Among them fish gills and skin were more affected followed by liver and kidney. Again when considered individual fish farm, fish of Pvt. Fish farms were more affected than others. The study showed that severity of clinically and pathologically changes were gradually increased in November to January. During the period mixed infection of protozoa, monogenea and argulus were noticed in catla of the investigated farms.

Clinical and histopathological studies were carried out with juvenile common carp (C. carpio) from a Government fish farm and a NGO fish farm in Mymensingh area for a period of 9 months from April 2005 to December 2005. Clinically red spots, scale loss, weak body, hemorrhage and subcutaneous lesion were noticed especially during November and December. A moderate pathological change in the investigated organs of all fishes were recorded in summer season (April-May), whereas in rainy season (June-July) pathological symptoms were significantly reduced which was again increased to some extent in the autumn season (August-September). However, marked pathological changes such as necrosis, protozoan cyst, bacterial colony, vacuum, melanomacrophase, hemorrhage, hypertrophy, hyperplasia and clubbing were recorded in all the investigated organs like skin, muscle, gill, liver and kidney in the months of October, November and December. Among the affected organs gills were more affected with the presence of numerous protozoan cysts followed by skin, liver and the less affected organ was the muscle. Clinically and histopathologically juvenile common carp of Government fish farm were more affected compare to NGO fish farm especially in colder moths of the year.DOI: http://dx.doi.org/10.3329/ijns.v1i4.9732 IJNS 2011 1(4): 77-81

Investigation on the health condition of small indigenous fish, Channa punctatus was carried out through clinical and histological observation from Jailka beel of Sherpur sadar, Sherpur district and Kailla beel of Ishargonj upazila, Mymensingh district for a period of six months from October 2014 to March 2015. Water quality parameters like water temperature, pH, dissolved oxygen, ammonia, total hardness, alkalinity and nitrate were recorded. Water temperature and total hardness were found at unfavorable level for fish in December and January. Clinical examinations of the fish were also carried out for any kind of abnormalities at monthly intervals. Clinically, it was observed that fish was affected with numerous red spots and patches in lateral and ventral regions, large deep whitish ulcers reached up to deep ulcers especially in December and January in both the beels. Samples of skin, muscle, gill, liver and kidney were collected and processed for histological observations. Major pathology in the skin and muscle were epidermis separated from dermis, presence of fungal granuloma, vacuums, hemorrhage and necrosis. Loss of primary and secondary gill lamellae, hypertrophy and primary gill lamellae separated, necrosis and hemorrhage were found in the gill. Large vacuums, necrosis and hemorrhage were observed in liver and kidney. Among the affected fish organs, skin and muscle, gills were found to be more affected than those of the internal organs like liver and kidney. Overall, under the clinical and histopathological observations the fish were found to be more affected in December and January. Whereas, in the months of February and March, the pathological condition of fish gradually healed up to normal except few vacuums and hemorrhage. Under histopathological observations, fish of Jailka beel were more affected than the fish of Kailla beel. In clinical and histopathological observation C. punctatus was more affected due to EUS.Asian J. Med. Biol. Res. September 2016, 2(3): 464-470

An experiment was carried out to investigate the health status of Hypophthalmichthys molitrix among three different fish farms at Mymensingh district of Bangladesh. Fish sampling and water quality parameters were collected on a monthly basis. Samples of skin, muscle, gills, liver and kidney were examined through histological technique. Results from water quality parameters suggested that water temperature had a distinct effect on fish health of H. molitrix, which was mostly evident during the colder months. Infectious symptoms were usually evident in July to October and the severity of pathology was increased in November and December. These were evident from their clinical signs that include scale loss, haemorrhagic lesion, and reddish spots or from their histopathological symptoms such as necrosis, pyknosis, inflammation, haemorrhage, hypertrophy, missing of gill lamellae, vacuums, tubular and pillar cells degeneration, inflammation, clubbing, and suspected bacterial colonies. Results suggest that the health condition of the fishes from BAU fish farm was the best over the other two farms, whereas Government fish farm followed by NGO fish farm were severely affected with EUS, protozoan and bacterial infection. Moreover, internal organs like liver and kidney were more affected than skin, muscle and gills.

The health status of the zebra-snout seahorse, Hippocampus barbouri in captivity has been required for approval for aquaculture. In this study, we investigated the histopathological appearance of three vital organs including gill, kidney and liver in captive H. barbouri during its juvenile and adult stages, by using histological techniques. In juveniles from stage 14-days (100% prevalence) towards stage 30-days adults (100% prevalence), the gills exhibited intraepithelial edema and necrosis while hepatic tissue showed evidence of intracytoplasmic vacuoles. In addition, histological alteration to renal tissues was observed the degeneration of renal tubules, the presence of melanomacrophage, and the infection of trematode parasites. The parasites were found in stage 30-days adult fish in the kidney (33.3 % prevalence). Taken together, this study highlights the issue of health in captive rearing of H. barbouri, in particular histopathological alterations in gill, liver and kidney tissues, suggesting that aquaculture of this seahorse species requires improved methods and protocols for maintenance and preventing infection.

This chapter looks at the health and lifestyle factors among tea garden labourers in West Bengal. Tea garden labourers enjoy access to some free facilities like education for children, medical facilities, piped drinking water, housing, and subsidised food. Yet they still suffer from several health problems. This might be due to insufficient or inadequately maintained facilities, poor lifestyles, or a mixture thereof. The chapter then focuses on the work environment, lifestyles, and physical health status of Oraon tea garden labourers of Jalpaiguri district, West Bengal. The results reveal that around 60 per cent of the labourers are underweight, despite reporting that they were getting sufficient food to eat. Poor hygienic practices may explain these results. Anaemia was also high for both sexes. Ultimately, the overall health condition of the labourers may be explained by the poor health lifestyles that they have adopted in response to their work environment.

Abstract Introduction E-cigarettes (ECs) may benefit smokers with mental health conditions who are more likely to smoke, and smoke more heavily, than those without mental health conditions. This could be undermined if harm misperceptions in this group are high as is the case in the general population. This study aimed to assess EC harm perceptions relative to cigarettes as a function of mental health status and a variety of characteristics. Methods Data were collected from 6531 current smokers in 2016/2017 in household surveys of representative samples of adults. The associations of mental health status (self-reported mental health condition and past year treatment), smoking and EC use characteristics, and characteristics relating to use of potential information sources with harm perceptions of ECs relative to cigarettes (measured by correct response “less harmful” vs. wrong responses “more harmful,” “equally harmful,” “don’t know”) were analyzed with logistic regression. Results A similar proportion of smokers without mental health conditions (61.5%, 95% CI 60.1–62.9) and with mental health conditions (both with [61.3%, 95% confidence interval [CI] 58.7–63.8] and without past year treatment [61.5%, 95% CI 58.1–64.7]) held inaccurate EC harm perceptions (all P &gt; 0.05). Being female, nonwhite, aged 25–34 compared with 16–24, from lower social grades (C2, D, and E), not having post-16 qualifications, no EC experience, a daily smoker, unmotivated to quit &lt;1 month, non-internet user and non-broadsheet reader were all associated with more inaccurate harm perceptions (all p &lt; .05). Conclusions The majority of smokers in England have inaccurate harm perceptions of ECs regardless of mental health status. Implications This study is the first to use a nationally representative sample in order to investigate whether smokers with and without mental health conditions differ with regard to harm perceptions of ECs. Findings show that the majority of smokers in England hold inaccurate harm perceptions of ECs, and this does not differ as a function of mental health status. A number of characteristics associated with disadvantaged groups were significantly associated with inaccurate harm perceptions. These findings highlight the need to improve awareness and understanding among disadvantaged groups regarding the relative harms of ECs compared with tobacco.

The article reports an innovative optical system that is designed to interrogate the health condition of macroscopically intact rail specimens by measuring its inherent nonlinearity using the narrowband Rayleigh waves. A line-arrayed pattern is developed through the optical system that generates narrowband Rayleigh waves with high power on the surface of the rail. As a result of lattice-anharmonicity, a second harmonic is produced in the wave that is sensed by a scanning laser Doppler vibrometer. The spectral amplitudes of the first and generated second harmonics are used to calculate the inherent nonlinearity using an amplitude-based nonlinearity equation. These measurements are carried out on the head, web, and foot of the rail. The performance of the non-contact experiment is also compared with that of a contact experiment carried out using wedge transducers. The experimentally evaluated nonlinearity of the rail steel is further compared with that obtained using a physics-based nonlinearity equation that relies on the higher-order elastic constants. Agreement of the results shows that the new optical system is effective in generating Rayleigh waves in rails and thereby measuring the inherent nonlinearity of the rail track. The estimation of inherent nonlinearity may help in diagnosing the health status of the macroscopically intact rail specimens in terms of their microstructural consistency and level of dissolved impurities before fixing them on a track.

Objectives: The present study was designed to estimate the influences of oral administration of aqueous extract of turmeric (Curcuma longa) in hepatotoxicity and nephrotoxicity induced in rats by isoniazid and rifampicin (RIF) for 4 weeks. Influences were determined through the estimation of liver and kidney functions and histopathological changes. Materials and Methods: A total of 48 male albino rats were randomly divided into six groups: Normal control, INH+RIF treated rats, Turmeric aqueous extract 100 mg/kg treated rats, Turmeric aqueous extract 100 mg/kg + INH and RIF treated rats, Turmeric aqueous extract 200 mg/kg treated rats, Turmeric aqueous extract 200 mg/kg+ INH and RIF treated rats. Turmeric aqueous extract and INH + RIF (50 mg/kg bwpo, daily) were given for 4 weeks. Liver and kidney function markers (aspartate transaminase [AST], alanine transaminase [ALT], alanine phosphatase [ALP], bilirubin, blood urea, and creatinine) were determined enzymatically. In addition, tissues of liver and kidney were quickly separated and fixed in 10% formalin and subjected to histopathological studies. Statistical analysis was carried out using t-test. Results: The aqueous extract of turmeric (at a dose of 100 and 200 mg/kg bw, p.o. daily ) showed hepato- and reno-protective effects in hepato- and reno- toxicity induced by RIF and INH in rats. Significant elevation of serum ALT, AST, ALP, total bilirubin, creatinine, urea, and total protein, due to RIF and INH treatment, were significantly decreased. The histopathological study further confirmed the biochemical results. Conclusion: Results of the present study indicated that turmeric has hepatoprotective and renoprotective action against RIF- and INH-induced hepatic and renal injury in rats.

Indoor smart-farming based on artificial grow lights has gained attention in the past few years. In modern agricultural technology, the growth status is generally monitored and controlled by radio-frequency communication networks. However, it is reported that the radio frequency (RF) could negatively impact the growth rate and the health condition of the vegetables. This work proposes an energy-efficient solution replacing or augmenting the current RF system by utilizing light-emitting diodes (LEDs) as the grow lights and adopting visible light communications and optical camera communication for the smart-farming systems. In particular, in the proposed system, communication data is modulated via a 24% additional green grow LED light that is also known to be beneficial for the growth of the vegetables. Optical cameras capture the modulated green light reflected from the vegetables for the uplink connection. A combination of white ceiling LEDs and photodetectors provides the downlink, enabling an RF-free communication network as a whole. In the proposed architecture, the smart-farming units are modularized, leading to flexible mobility. Following theoretical analysis and simulations, a proof-of-concept demonstration presents the feasibility of the proposed architecture by successfully demonstrating the maximum data rates of 840 b/s (uplink) and 20 Mb/s (downlink).
