Objective: To evaluate the antineoplastic activity of Eucalyptus extract (EuE) against Ehrlich ascites carcinoma (EAC) in Swiss albino mice. Methods: Preliminary examination of four plant extracts (namely Eucalyptus, Costus, Azadirachta, Feronia) has been done by observing the reduction ability of number of EAC cells in previously inoculated Swiss albino mice. Among them as EuE showed maximum capability, the whole study has been conducted with EuE only. Important parameters viz. enhancement of life span, reduction of average tumor weight etc. have been studied. In addition the effects of EuE on hematological parameters in both normal and EAC inoculated mice have been measured. Effect of EuE on normal peritoneal cells has also been studied. Results: EuE reduced tumor burden remarkably. It reduced the tumor growth rate and enhanced the life span of EAC bearing mice noticeably. It reversed back the hematological parameters towards normal, reduced the trasplantability of EAC cells and enhanced the immunomodulatory effects in mice. The host toxic effect of EuE in mice is minimum and mostly reversible with time. All such data have been compared with those obtained by running parallel experiments with bleomycin at dose 0.3 mg/kg (i.p.). Conclusions: The Eucalyptus extract may be considered as a potent anticancer agent for advanced researches.

OBJECTIVETo determine the hepatoprotective effect of acetone semicarbazone (ASC) in vivo in normal and Ehrlich ascites carcinoma (EAC) bearing male Swiss albino mice.
METHODSDrug-induced changes in biochemical and behavioral parameters at dose of 2.0 mg/kg body weight for 14 d and nullifying the toxicity induced by EAC cells were studied. The histopathology studies of the protective effects of ASC on vital organs were also assessed.
RESULTSThe administration of ASC made insignificant changes in body weight and behavioral (salivation, diarrhea, muscular numbness) changes during treatment period due to minor toxicity were minimized after the treatment in normal mice. The biochemical parameters, including serum glutamate pyruvate transaminase, glutamate oxaloactate transaminase, alkaline phosphatase, serum glucose, cholesterol, urea, triglyceride and billirubin changed modestly in normal mice receiving ASC. Though the treatment continued, these values gradually decreased to normal level after the treatment. In EAC bearing mice, the toxic effects due to EAC cells in all cases were nullified by treatment with the ASC. Significant abnormalities were not detected in histology of the various organs of the normal mice treated with ASC.
CONCLUSIONSASC can, therefore, be considered safe in formulating novel anticancer drug, as it exhibits strong protective effect against EAC cell bearing mice.

Objective: To investigate the comparative effects of Diospyros blancoi (Ebenaceae) leaves (DBL), root bark (DBRB) and stem bark (DBSB) on free radicals and cancer. Methods: The polyphenol contents, antioxidant and free radical scavenging properties were determined using standard spectrophotometric methods. Cytotoxicity and anticancer activ-ities were performed on brine shrimp nauplii and Ehrlich ascite carcinoma cells, respectively. Results: Among the extracts, DBSB showed the highest total antioxidant capacity and reducing capacity on ferrous ion. Based on 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radical scavenging activities, DBSB showed (95.760 ± 0.343)%and (67.460 ± 2.641)%scavenging with IC50 of (3.10 ± 0.17) and (50.00 ± 3.11) mg/mL, respectively. The IC50 values of standard butylated hydroxytoluene and catechin (CA) for 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radicals were (8.50 ± 0.25) and (75.00 ± 0.14) mg/mL, respectively suggesting that DBSB had a significant (P < 0.05) radical scavenging ac-tivity than standards. In lipid peroxidation inhibition assay, the inhibitory activity of the extracts and the standard was in the following order: DBSB > DBRB > CA > DBL. Also, the phenolic [(139.91 ± 3.924) mg gallic acid equivalent/g] and flavonoid contents [(412.00 ± 16.70) mg catechin equivalent/g)] of DBSB were higher than that of other extracts. In addition, the DBSB showed the moderate cytotoxic and anticancer properties. Conclusions: Our results indicate that Diospyros blancoi stem bark had the significant highest antioxidant and free radical scavenging properties as well as moderate anticancer activity. Hence, we assume that the anticancer activity of this plant can be, at least in part, attributed to its content in phenolic compounds as well as its significant free radical scavenging properties.

Objective: To study the phytochemical and biological properties (antioxidant, anthelmintic and thrombolytic) of methanolic extracts of Enhydra fluctuans Lour., a plant belonging to the Asteraceae family.
Methods:The phytochemical evaluation was carried out by qualitative analysis. In vitro antioxidant activity of extract was studied using free radical scavenging assay, ability of reduction, total phenol and total flavonoid contents determination assays. The anthelmintic activity was determined using paralysis and death time of Pheretima posthuma (earthworm) and thrombolytic activity by clot disruption assay.
Results:The phytochemical evaluation showed significant presence of flavonoids, triterpenes,carbohydrate, reducing sugars, saponins, phenols, diterpenes, protein and tannin. The antioxidant activity was found significant [IC50=(135.20±0.56) μg/mL] as compared to ascorbic acid [(130.00±0.76) μg/mL]. The reducing power was increased with concentration. Total phenol and total flavonoid contents were (153.08±0.38) mg/mL and (172.04±0.56) mg/mL respectively. The paralysis and death time of earthworms for different concentrations of extract were determined and compared with albendazole. The results showed that 10 mg/mL of the crude extract had similar effect with albendazole. Additionally, the crude extract showed a concentration depended relationship with its anthelmintic property. The clot lysis activity of crude extract was compared to the standard streptokinase’s clot lysis (40.13%) activity and found significant (31%).
Conclusions: The study proves that the crude methanolic extract of Enhydra fluctuans Lour. has significant antioxidant, anthelmintic and thrombolytic activity containing wide range of phytochemicals.

A newly synthesized Nickel (II) tyrosine complex was screened as potential antimicrobial agent against a number of medically important bacteria (Bacillus subtilis, Streptococcus beta-haemolytica, Escherichia coli, Shigella dysenterae) and fungi (Aspergillus fumigatus, Candida albicans, Aspergillus niger, Aspergillus flavus, Penicillium sp.) strains. were used for antifungal activity. The antimicrobial activity was evaluated using the Agar Disc method. Moreover, the minimum inhibitory concentration of the complexes was determined against the same pathogenic bacteria and the values were found between 4~64 microg ml(-1). Brine shrimp bioassay was carried out for cytotoxicity measurements of the complexes. The LC50 values were calculated after probit transformation of the resulting mortality data and found to be 6 microg ml(-1).

The aim of this study was to assess changes of Hsp70 and HSF-1 protein and mRNA expression in stress-sensitive organs of pigs during transportation for various periods of time. Twenty pigs were randomly divided into four groups (0 h, 1 h, 2 h, and 4 h of transportation). A significant increased activity of AST and CK was observed after 1 h and 2 h of transportation. Histopathological changes in the heart, liver, and stomach indicated that these organs sustained different degrees of injury. Hsp70 protein expression in the heart and liver of transported pigs did not change significantly while it increased significantly (p < 0.05) in the stomach. Hsp70 mRNA levels decreased significantly (p < 0.05) in the heart after 4 h of transportation. However, mRNA expression increased significantly in the liver after 1 (p < 0.05) and 4 h (p < 0.01) of transportation, and increased significantly in the stomach of the transported pigs after 1, 4 (p < 0.01), and 2 h (p < 0.05). HSF-1 levels were reduced at 1 and 4 h (p < 0.05) only in the hearts of transported pigs. These results indicate that Hsp70 mediates distinct stress-related functions in different tissues during transportation.

Introduction: This study aimed to assess the effectiveness of dental plaque removal and to determine factors that could influence its efficacy when using the non-dominant hand. Methods: A quasi-experimental study was performed on a group of dental students. Dominant hands were determined using Edinburg Handedness Inventory questionnaire, and the dental plaque scores were examined using Quigley-Hein (Turesky) index. All of the participants were examined twice for dental plaque index scores. Data obtained was analyzed using a paired t-test and an independent t-test. Factors which influenced the dental plaque removal were listed and categorized accordingly. Results: A total of 62 dental undergraduates participated in the study. A high percentage of them, (71%, n = 44) were found to be right-handed. There was a significant increase in the dental plaque score for the left-handed participants, from baseline (use of the dominant hand) to follow-up appointment (after brushing their teeth with non-dominant hands) (p< 0.01). A significant change was found between the right- and left-handed participants in the first quadrant of the buccal side (p<0.05). Factors identified to be beneficial in dental plaque control were; using a mirror while brushing, extending brushing time, increasing brushing frequency, using additional tooth aids and powered toothbrushes. Conclusions: This study revealed that left-handed participants have less ability to remove dental plaque with their non-dominant hands. The right-handed participants, showed better controls in plaque removal with their non-dominant hands, compared to their left-handed peers on the buccal side of the first quadrant.

Objectives:
To assess the prevalence of noncommunicable disease (NCD) risk factors and the factors associated with the coexistence of multiple risk factors (≥ 2 risk factors) among adolescent boys and girls in Bangladesh.
Methods:
Data on selected NCD risk factors collected from face to face interviews of 4,907 boys and 4,865 girls in the national Nutrition Surveillance round 2018-2019, was used. Descriptive analysis and multivariable logistic regression were performed.
Results:
The prevalence of insufficient fruit and vegetable intake, inadequate physical activity, tobacco use, and being overweight/obese was 90.72%, 29.03%, 4.57%, and 6.04%, respectively among boys; and 94.32%, 50.33%, 0.43%, and 8.03%, respectively among girls. Multiple risk factors were present among 34.87% of boys and 51.74% of girls. Younger age (p < 0.001), non-slum urban (p < 0.001) and slum residence (p < 0.001), higher paternal education (p = 0.001), and depression (p < 0.001) were associated with the coexistence of multiple risk factors in both boys and girls. Additionally, higher maternal education (p < 0.001) and richest wealth quintile (p = 0.023) were associated with the coexistence of multiple risk factors in girls.
Conclusion
The government should integrate specific services into the existing health and non-health programs which are aimed at reducing the burden of NCD risk factors.
