RESUMO
Aim: The objective of the study was to assess the effect of dietary incorporation of different feed attractants viz. tubifex, earthworm and fish meal on growth and survival of O. bimaculatus (pabda fish) fry. Methodology: Fifty numbers of fifteen days weaned fry (0.105±0.008g; 2.14±0.14cm) were stocked into each aerated aquariums (30.0 x 15.0 x 15.0 cm) following a completely randomized design (CRD) consisting of four treatments including the control with three replicates each. Four iso-nitrogenous purified diets were prepared including three treatment diets with attractants (5%) by replacing an appropriate amount of casein and cellulose and fed to the fishes twice daily. Results: Results from the study showed that growth of fry as measured by final weight, weight gain, mean daily weight gain and specific growth rate of fries were significantly (p<0.05) higher in tubifex supplemented group and lower in control group. Survival was significantly higher in tubifex supplemented group (42.66±1.3%) and lower in control group. Moreover, other yield parameters such as total biomass, condition factor and performance index also followed the same trend as survival. Further, higher protease activity was found in control group (2.233±0.038 units mg protein-1 min-1) followed by earthworm (0.354±0.031 mg protein-1 min-1) supplemented group (p<0.05). The lipase and amylase activity were higher (p<0.05) in tubifex and control groups, respectively. Interpretation: It could be concluded that the dietary supplementation of tubifex at 5% inclusion level could be a promising aquaculture feeding strategy for pabda fish due to its rich nutrient content, increased feeding stimulation and more palatability.
RESUMO
Background: Oral submucous fibrosis is very common in Asia. It has many deleterious effects on individual's oral functions. Thus, there is a need to assess the effect of oral submucous fibrosis on quality of life. Objective: To assess the oral health-related quality of life (OHRQoL) in male subjects with oral submucous fibrosis. Methods: Two hundred and thirty male subjects in the age range of 20–40 years were recruited in the cross-sectional, two-group comparative study. Of 230 male subjects, 115 were oral submucous fibrosis subjects who were included in the study group and 115 healthy subjects formed the control group. English version of the oral health impact profile-14 (OHIP-14) was used to assess the OHRQoL. Wilcoxon signed-rank, Kruskal–Wallis, and Bonferroni tests were applied, and the P = 0.05 was considered as level of significance. Results: The mean and median OHIP-14 scores were 19.10 ± 0.66 and 18.00 in the study group and 3.98 ± 3.80 and 3.00 in the control group subjects, respectively (P < 0.001). Mean score of all the seven domains of OHIP-14 was significantly more in oral submucous fibrosis subjects (P < 0.001). All the oral submucous fibrosis subjects had one or more negative effects on OHRQoL compared to 64.34% of healthy subjects. Stage-4 of the oral submucous fibrosis had maximum effect on quality of life compared to other stages (P < 0.001). Conclusions: The quality of life among males is severely affected by oral submucous fibrosis, and Stage-4 of oral submucous fibrosis has maximum effect on the quality of life.
