Background: Urine sediment examination provides numerous information about patient's kidney condition. Flowcytometry and digital imaging system could conduct automatic urine sediment analysis. Therefore, determining the diagnostic performance of the examination is very important in the management carried out by the clinician. This study aims to determine the diagnostic performance of urine flowcytometry and digital imaging sediment examination tools compared to manual microscopes that are standardized as gold standards. Methods: This study is an analytical observational study with a cross-sectional approach on 92 urine samples of patients who attended the Internal Medicine Nephrology Polyclinic of Dr. Soetomo Academic Hospital Surabaya. The performance of flowcytometry and digital imaging methods is assessed by calculating sensitivity and specificity. Analysis of the suitability of each urine sediment parameter used Cohen's kappa. Urine sediment analysis with a light microscope was conducted with the Shih-Yung method as a gold standard. Results: The erythrocyte parameters revealed a very favorable result with the concordance of the flowcytometry with the Shih-Yung method (κ=0.82) and fair results for WBC (κ=0.25), Epithelium (κ=0.57) and Cast (κ=0.27). At the same time, yeast had substantial conformity (κ=0.63). The digital imaging method showed substantive fit for WBC (κ=0.676), RBC (κ=0.621), fair for SEC (κ=0.42) and NSE (κ=0.24), moderate for Yeast (κ=0.45), and slight for Hyaline Cast (κ=0.074) and Path Cast (κ= 0.134) Conclusion: The urine flowcytometry demonstrates better performance compatibility with a standardized manual microscope compared to urine digital imaging. However, pathological samples should still be verified with a manual microscope. [ABSTRACT FROM AUTHOR]

Background: Galinsoga parviflora is a medicinal plant traditionally used to manage and treat various health conditions though the dearth of its scientific report on its pharmacognostic and safety profile remains. Objective: This study is designed to delineate the pharmacognostic and safety parameters of G. parviflora to ensure its authenticity, purity, quality, and safety. Methods: Qualitative and quantitative analysis, including physicochemical evaluation, macroscopic and microscopic characterization, phytochemical screening, and acute toxicity test, were carried out to establish the plant's diagnostic features and safety needed for its identification and standardization. For the Acute toxicity test, male and female rats were orally administered with aqueous extract at a single dose of 2000 mg/kg (n=5/sex) and 5000 mg/kg (n=3/sex). All experimental animals were critically observed individually for overt signs and symptoms of toxicity, behavioral changes, body weight changes, and mortality for 14 days. Results: The physicochemical characterization, macroscopic evaluation, morphometric determination, surface tissue examination, and powder analysis of the intact and powdered drug material revealed key diagnostic features and properties based on the stem, leaf, flower architecture, and pharmaceutical properties. The aqueous extract primarily contains alkaloids, glycosides, flavonoids, saponins, phytosterols, and tannins as its phytoconstituents. During the acute toxicity test, no toxicological response and mortality were observed on both doses. Conclusion: The present study provides vital architectural features and chemical characteristics of G. parviflora essential for establishing pharmacopoeial standards, especially in plantbased medicine. Additionally, the aqueous extract's oral dose of up to 5000 mg/kg is relatively safe as no significant evidence of treatment-related toxicity and mortality is seen. [ABSTRACT FROM AUTHOR]

Background: In ethno-medicinal practices, the leaves of Alocasia macrrorhizos, Canavalia ensiformis, Amaranthus cruentus, Averrhoea carambola, Bauhina tenifloara, and Capsicum Chinese have different pharmacological activities. The problem encountered with the proper utilization of herbal drugs is lack of documentation and standard parameter, which create problem in acceptance and importance of these plants. Objective: The objectives of our study are to establish scientifically evaluated pharmacognostic profile and in vitro antiinflammatory screening of six plants. Methods: Leaf sample from each plant was evaluated by macroscopic, microscopic and physicochemical parameters (As per WHO recommended methods of standardization).

Background: Piper betle L. is a well-known and widely used herb especially in tropical Asiatic countries, which contains several bio-active constituents and possesses health promoting properties. The leaves of Piper betle L. have been traditionally known for its various therapeutic uses. The pharmacognostical and physicochemical investigations have not been carried out for eastern Piper betle cultivars. Objective: The present investigation was therefore undertaken to determine the requisite pharmacognostic standards for their evaluation to ensure their safety and efficacy. Materials and methods: Different Piper betle L. cultivars (Desi, Bangla, Kali, Haldia, Sanci, Meetha, Birkoli and Magahi) were obtained from Indian States of West Bengal, Odisha, and Bihar (Table 1). Fresh leaves were washed with water, sliced with a microtome and the transverse sections were stained with safranin, phloroglucinol, concentrated hydrochloric acid and mounted in glycerine medium. Leaves dried in the shade were finely powdered and passed through a sieve no.180 and a sieve no.125, separately, to obtain fine powder respectively and then subjected to microscopic examination. Mesophyll tissue is divided up by slendest vein, which is called vein islet. The numbers of vein islet in every epidermal cell is called Vein Islet Numbers (VIN); Vein termination number is the number of veinlet termination per square mm of the leaf surface midway between the midrib and the margin (VTN). Since vein islet and vein termination number is consistent and different from plant to plant, this parameter can be used in authentication. Stomatal Index (SI) is a basilic parameter in authentication, which can be obtained from the following formula: Stomatal Index 1/4 (number of stomata/every millimeter- square) × 100/(number of stomata/every millimeter-square + number of epidermal cell/every millimeter - square), which also can be used as a reliable parameter in authentication since it is consistent in a species of plant. The results were studied using light microscope according to the usual microscopic techniques. Different physicochemical parameters such as ash value, extractive value and loss on drying were carried out as per WHO guidelines. Results: In present study eight cultivars of Piper betle were compared with their distinguishing morphoanatomic details of leaf, dissociation and powders. The microscopic features were systematically described and illustrated. The physiochemical properties such as loss on drying, total ash value, acid insoluble ash value, water soluble ash value and extractive values were also carried out. HPTLC analysis of petroleum ether extract and essential oil showed confirming the presence of compound in Piper betle cultivars leaf. And detailed key authentication parameters based on these anatomic characteristics were presented. The various morphological, microscopical, physicochemical standards can be unambiguously used to authenticate standardization and distinguish eight cultivars of Piper betle. [ABSTRACT FROM AUTHOR]
