Status of organic carbon (C), total nitrogen (N), available potassium (K), calcium (Ca) and phosphorus (P) in three different depths (0-5 cm, 5-15 cm and 15?30 cm) on two hill slopes of 35% and 55% in orange orchard cultivated by the Mro tribe of Chittagong Hill Tracts (CHTs) were evaluated and compared with those in degraded bush forests, through digging three profiles in each land use. The content of all the five nutrients was found to be higher in the soil of orange orchard than in the soil of forest. But the variation was not consistent for both the slopes. The content varied depth wise also, having the highest value in surface soil in case of both the land uses on both the slopes. A mean available K content was significantly higher in orange orchard than in forest on 55% slope, while it was lower on 35% slope. Surface soil contained the nutrients of K and Ca with the amount of 0.2905-mg·g^(-1) soil and 3.025-mg·g^(-1)soil respectively in the orchard, while 0.1934-mg·g^(-1) soil and 1.6083-mg·g^(-1) soil were respectively in the forest. Organic carbon and total nitrogen were found more or less similar in surface soil on both the land uses showing a slight difference. Available P was found only in orange orchard, and in forest it was too little in amount to detect by the spectrophotometer. The degraded forests were poor in nutrient content due to high rate of soil erosion, which would be possible to be improved by bringing it under tree cover as proved by the adaptation of orange orchard there.

The acceptability and physicochemical qualities of carambola candy were evaluated in order to increase fruit consumption. The goal of this investigation was to see whether there were any techniques to preserve carambola in the form of candy. Sugar in various forms (white sugar, corn syrup, icing sugar, and molasses) was employed in candy making process in this study. Moisture, protein, fat, ash, vitamin C, total sugar content, organoleptic quality and microbial status of the prepared candy were analyzed. Protein, fat, vit-C, and total sugar content of carrambola candy were found to be higher with white sugar solution but moisture and ash content was found to be higher with molasses. On the microbiological analysis, total fungal growth was tested visually at 0 to 90 days and compared with refrigeration and room temperature. Fungal growth was found at 90 days at room temperature for all types of carambola candy. Sensory attributes revealed that sample 2 (corn syrup-based candy) was most delicious and appreciated among other samples. The best characteristic of carambola candy was found with white sugar solution, with sufficient nutrient and lowest fungal growth than candy prepared with corn syrup, icing sugar solution and molasses.

Cheese has recently gained a lot of popularity around the world. This experiment was carried out to make cheese from skim milk with the addition of garlic paste. This study focused on the impact of garlic paste on the physicochemical properties of cheese. Cheese samples S1, S2, S3, and S4 were prepared with 0%, 1%, 3%, and 5% garlic paste, respectively, where S1 was the control sample. Compared to sample S1, the higher proportion of garlic paste incorporation resulted in higher viscosity and water holding capacity;nevertheless, lower values for syneresis were obtained. Although no significant change was observed in the pH values, samples S4 (5% garlic) and S1 (0% garlic) exhibited the highest and lowest pH, respectively. The results in this investigation revealed that garlic inclusion had a substantial impact on the physicochemical parameters of the skim milk cheese.

作者： Mohammad Shaheed Hossain Chowdhury md. abdul halim Nur Muhammed Farhana Haque Masao Koike Forest Policy Laboratory Department of Forest ScienceFaculty of AgricultureShinshu University Department of Forestry and Environmental Science School of Agriculture and Mineral SciencesShahjalal University of Science and Technology

A study was conducted to explore the traditional utilization pattern and indigenous management practices of wild date palm （Phoenix sylvestris Roxb） in the rural agrarian regions of Bangladesh. A multistage sampling method with 10% intensity and a semi-structured questionnaire were used for the study. The farmers manage the palm mainly for sap production with which sugar based secondary goods are manufactured. The sap is either used fresh as drink or after some sort of processing as molasses and/or alcoholic beverage. Seven diversified sites support the palm as its habitat and most palms （20.40%） occur in orchards. Besides growing naturally, the palm is also established in orchards using the wildings as the staple planting material. Although the medium category farmers own most of the palms （33%）, a considerable portion （28.68%） of it is managed by the landless farmers, who earn a substantial livelihood from the palms. The farmers practice their own indigenous wisdom in every stage of the palm＇s maintenance from planting through tapping for sap collec- tion to the processing of products. If managed more scientifically on a sustainable basis with the collaboration of farmers＇ indigenou~ knowledge, this familiar palm could be able to support the rural economy of the country to a great extent. Side by side, it would also be able to contribute to the richness of biodiversity in the region.

A study was conducted to investigate the land-use pattern change over a period of 18 years （1988-2006） by using remote sens- ing and Geographical Information System （GIS） technologies, in the West Bhanugach Reserved Forest, a hill forest, in Sylhet Forest Divi- sion of Bangladesh, The images were processed using ERDAS Imagine software. Both supervised and unsupervised approaches were ap- plied and ground control points were collected using a GPS. Maps were prepared using GIS software. Results showed that vegetation cover drastically decreased from the year 1988 to 1996 （l 826 ha to l 714.85 ha）, but increased gradually from the year 1996 to 2006 （l 714.85 ha to l 847.83 ha） due to the initiation of co-management practice involving local communities. Change in bare land was inversely proportionate to the amount of vegetation cover changes unless any other land-uses were converted into bare land. The area of water bodies increased from the year 1988 to 1996 （307.67 ha to 379.53 ha）, but decreased from the year 1996 to 1997, then remained invariabile from the year 1997 to 2006. Some recommendations were also made for applying the RS and GIS techniques to study the land-use pattern change in the Bhanugach Reserved Forest and to create a GIS data base for the study area.

This study examines the effects of heat, mass, and boundary layer assumptions-based nanoparticle characteristics on the hybrid effects of using MHD in conjunction with mixed convective flow through a sloped vertical pore plate in the existence of medium of porous. Physical characteristics such as thermo-diffusion, injection-suction, and viscous dissipation are taken into consideration, in addition to an equally distributed magnetic force utilized as well in the completely opposite path of the flow. By means of several non-dimensional transformations, the momentum, energy, concentration, and nanoparticle volume fraction equations under investigation are converted in terms of nonlinear boundary layer equations and computationally resolved by utilizing the sixth-order Runge-Kutta strategy in combination together with the iteration of Nachtsheim-Swigert shooting procedure. By contrasting the findings produced for a few particular examples with those found in the published literature, the correctness of the numerical result is verified, and a rather good agreement is found. Utilizing various ranges of pertinent factors, computing findings are determined not only regarding velocity, temperature, and concentration as well as nanoparticle fraction of volume but also concerning with local skin-friction coefficient, local Nusselt and general Sherwood numbers associated with nanoparticle Sherwood number. The findings of the study demonstrate that increasing the fluid suction parameter decreases the velocity and temperature of the flow field in conjunction with concentration and has a variable impact on the nanoparticle fraction of volume, despite an increasing behavior in the local skin friction coefficient and local Nusselt as well as general Sherwood numbers and an increasing behavior in the local nanoparticle Sherwood number. Furthermore, enhancing a Schmidt number leads to a reduction in the local nanoparticle Sherwood number and a rise in the nanoparticle proportion of vo

The physical properties of soil on two hill slopes of 35% and 55% in orange orchard cultivated by the Mro tribe of Chittagong Hill Tracts （CHTs） were evaluated and compared with those of bushy hill forests. Soil samples were collected from three different depths （0-5 cm, 5-15 cm and 15-30 cm）, digging three profiles in each land use for determining moisture content, organic matter content and particle density. Maximum water holding capacity, field capacity, dry and moist bulk density and porosity were determined only for the surface soils. Moisture content at all the soil depths was significantly higher （p≤ 0.05） in orange orchard than in forest on both the slopes. Orange orchard contained lower mean soil organic matter than forest on 55% slope, while it contained higher values on 35% slope compared to forest. The highest value of the above two properties was found at surface soil in both the land uses on both the slopes, decreasing with the increase of soil depth. On both the slopes maximum water holding capacity and porosity of surface soil and particle density at all soil depths were lower in orange orchard compared to those in forest. Field capacity values of surface soil did not show consistency in trend for the differences between the two land uses on both the slopes. Bulk density value of moist and dry surface soil was higher in orange orchard than in forest on both the hill slopes.

Antinociceptive Effect of Ethanolic Extract of Codiaeum variegatum Leaves in Mice

引用

Pharmacology & Pharmacy 2024年第9期15卷 285-302页

作者： md. Asrafuzzaman Ambia Khatun md. abdul Mannan Department of Pharmacy Stamford University Bangladesh Dhaka Bangladesh

Background: Codiaeum variegatum, sometimes called garden croton, is a tropical plant in the Euphorbiaceae family. Historically used to cure various conditions, including intestinal infections, fever, ulcers, wounds, and gonorrhea. This work aimed to investigate the antinociceptive effects of ethanolic extract of Codiaeum variegatum leaves (EECV) in animal models. Methods: Five different pain models—the hot plate, tail immersion, acetic acid-induced writhing, formalin, and glutamate-induced nociception tests—were utilized to assess the antinociceptive activity in mice. The traditional drugs such as diclofenac sodium (10 mg/kg, i.p.) and morphine sulphate (5 mg/kg). EECV was administered orally at varying doses of 100, 200, and 300 mg/kg (0.1 mL/mouse), while the control group was given deionized water. Results: The current study found that all mouse models of heat- and chemical-induced pain had robust EECV reflections of their antinociceptive properties (*p Conclusions: The current finding offers a fresh perspective on the ethanolic extract of Codiaeum variegatum leaves’ antinociceptive properties in mice. This plant’s phytochemical analysis revealed the presence of triterpenoids, sterols, alkaloids, flavonoids, and general glycosides, all of which may have antinociceptive properties. More research on the mechanism of action and associated pharmacological studies, such as in vivo analysis, medication formulation, and clinical trials, is strongly advised.
