Abstract

Crossing over is the occurrence of disconnection and reconnection followed by a reciprocal exchange between the two chromatids in a bivalent form. The crossing event will produce parental type and recombinant type. In the event of crossing over, various factors can influence it. These factors can be due to internal and external. Recently, various factors have been reported that influence the incidence of crossing over. These factors include age, temperature, radiation, and changes in chromosome structure. This research is a type of experimental research that uses a randomized block design. Randomized block design by crossing D. melanogaster strains ?N>< ?bcl and ?N>< ?ym and their reciprocals. From the results of this cross (F1) then cross again ?N with the recessive male (from stock) then observe the phenotype of the offspring (F2) and calculate the results of the offspring. The F2 ?N crosses were treated with age variations, namely 0, 3, 6, 9, 12, 15, and 18 days. Based on the results of these crosses, the derived strains that appeared in the F2 crosses showed the phenomenon of crossing over with the influence of the age of the female and the type of strain on crossing events. the frequency or value of crossing over (formation of recombinants) decreased with the increasing age of the female. If the age of the female affects the frequency of crossing over, then the older the female, the more likely the frequency of crossing over will decrease. However, because the data obtained were incomplete, it was not possible to know the effect of female age on the frequency of crossing over of D. melanogaster crosses ?N>< ? bcl and ?N >< ?ym and their reciprocals. The condition for crossing over is the formation of a synaptonemal complex. Age of D. melanogaster females has an effect on the frequency of crossing over in crosses N? >< bcl?, N? >< ym?, and their reciprocals. The older Drosophila melanogaster is, the lower the frequency of crossing over will occur. Based on this, it was necessary to cross D. melanogaster with strains N, bcl, and ym. A cross consists of ?N ><?bcl and ?N ><?ym and their reciprocals. By crossing ?N with a recessive male from the stock, then observing the F2 phenotype, it is hoped that crossing over will occur. So that you can better understand by doing the practice directly. In this case, the effect of crossing over is seen from the age of the female and the type of strain.

Abstract

The leaf of Paederia foetida L. is one type of medicinal plant that can be used as a preventive medicine for sepsis. This plant contains secondary metabolites such as alkaloids, flavonoids, triterpenoids, saponins, and other active compounds. The objective of this study was to determine the histopathological description of the liver in a mouse sepsis model infected with E. coli, with the administration of Paederia foetida L. leaf extract for sepsis prevention, and to ascertain the influence and effective dosage of the leaf extract as a preventive measure against liver histopathology in the sepsis model induced by E. coli. The method employed was a Completely Randomized Design (CRD). The study used 24 male white mice divided into 6 (six) groups. Data analysis was conducted using One Way ANOVA. The results of the study revealed the histopathological profile of liver cell degeneration in group PI (100mg/kg BW) at 20.79%±0.03, group PII (200mg/kg BW) at 21.63%±0.02, and group PIII (500mg/kg BW) at 9.08%±0.02. Necrosis rates were observed in group PI (100mg/kgBW) at 22.62%±0.04, group PII (200mg/kg BW) at 17.63%±0.02, and group PIII (500mg/kg BW) at 6.05%±0.02. The presence of polymorphonuclear leukocytes (PMN) was detected in group PI (100mg/kgBW) at 39.56%±0.03, group PII (200mg/kgBW) at 28.05%±0.02, and group PIII (500mg/kg BW) at 18.45%±0.03. The test results showed a significant effect of P. foetida L. leaf extract as a preventive measure against liver histopathology in the mouse sepsis model infected with E. coli, with significant values for necrosis (p=0.000), cell degeneration (p=0.000), and PMN (p=0.000). The most effective dosage of P. foetida L. leaf extract as a preventive measure against liver histopathology in the mouse sepsis model infected with E. coli was the dosage used in group PIII (500mg/kgBW).

Abstract

Sepsis is a life-threatening condition characterized by an abnormal immune response to infection, leading to high mortality rates in intensive care units (ICUs) worldwide. Caspase-3, a crucial enzyme in the apoptosis pathway, plays a significant role in sep-sis-related cellular damage. This study investigates the anti-apoptotic potential of Paederia foetida L. leaf extract by examining its effect on Caspase-3 expression in an Escherichia coli-induced sepsis mice model. Male Balb/c mice were divided into six groups, including positive control, negative control, and treatment groups receiving varying doses of the extract (100 mg/kgBW, 300 mg/kgBW, and 500 mg/kgBW). Caspase-3 expression in the spleen was measured after 24 hours of treatment. The results demonstrated a significant reduction in Caspase-3 expression, particularly in the group treated with 500 mg/kgBW of the extract, indicating its anti-apoptotic effect. These findings suggest that P. foetida leaf extract may serve as a potential therapeutic agent for reducing cell apoptosis in sepsis, warranting further investigation into its mechanisms and clinical pharmacological field.

Abstract

Sepsis is a critical medical condition characterized by a systemic immune response to in-fection, which can lead to severe organ dysfunction and mortality. Bacterial sepsis, par-ticularly caused by Escherichia coli, poses a significant risk due to its potential to harm tissues and organs, including the liver. The liver plays a central role in metabolic process-es and host defense during sepsis, making it a key organ of interest. This study aimed to investigate the effect of Paederia foetida leaf extract on liver weight in a mice sepsis mod-el. Mice were divided into six groups: normal control (N), negative control (K-) receiving distilled water, positive control (K+) receiving ciprofloxacin, treatment 1 (P1) receiving P. foetida extract at 100 mg/kg BW, treatment 2 (P2) receiving 300 mg/kg BW, and treat-ment 3 (P3) receiving 500 mg/kg BW. After 14 days of treatment, significant differences in liver weight were observed among the groups, with the highest mean and standard de-viation recorded in the P1 group (1.3750 ± 0.3932). Liver abnormalities, including swell-ing, lobular thickening, and weight increase, were identified, indicating the liver’s adap-tive response to toxic substances during sepsis. Interestingly, the normal control group exhibited higher liver weights compared to the treatment groups, possibly due to fatty substance accumulation within the liver tissues. These findings suggest that P. foetida ex-tract may influence liver weight changes in sepsis, potentially modulating metabolic and detoxification processes. Further studies focusing on histopathological and biochemical mechanisms are needed to clarify the therapeutic potential of P. foetida in managing liver dysfunction associated with sepsis.

Abstract

Gastroenteritis, a widespread condition characterized by inflammation of the stomach and intestines, poses significant health challenges globally. Conventional treatments primarily focus on symptomatic relief and do not address the underlying gastric mucosal damage. Peperomia pellucida L., a medicinal plant known for its anti-inflammatory and antioxidant properties, has been suggested to possess gastroprotective effects. This study aims to evaluate the histopathological effects of P. pellucida L. on gastric protection in a mouse gastroenteritis model. Male Swiss mice were divided into six groups, receiving different treatments, including the ethanol extract of P. pellucida at varying doses (100, 300, and 500 mg/kgBW), followed by induction of gastroenteritis with Escherichia coli. Histopathological analysis was conducted to observe tissue damage across the treatment groups, including necrosis and cell degeneration. The results revealed that P. pellucida L. exhibited significant gastroprotective effects, particularly at a dose of 500 mg/kgBW, reducing gastric mucosal necrosis and inflammation compared to the control groups. The plant’s secondary metabolites, including flavonoids, tannins, saponins, and alkaloids, contributed to the observed protective effects by enhancing mucus production, reducing gastric acidity, and promoting tissue repair. These findings suggest that P. pellucida L. could be an alternative treatment for gastroenteritis and related gastric conditions, offering a natural approach to managing gastric inflammation and mucosal protection.

Abstract

Mistletoe (Dendrophthoe pentandra (L.) Miq.) is one of the plants found in Indonesia. The type of mistletoe commonly found is D. pentandra (L.) Miq. Apart from its parasitic nature, the leaves of D. pentandra (L.) Miq. has useful benefits as an antibacterial. Bacteria are divided into two groups based on their staining, namely Gram-positive bacteria and Gram-negative bacteria. Infectious diseases can be caused by several types of microorganisms in the bacterial group, including Pseudomonas aeruginosa. This study aims to determine the P. aeruginosa bacteria in the extract of lime mistletoe. This study used an experimental post-test only control research design with the disc diffusion method. This study used five concentrations, namely 20%, 40%, 60%, 80%, and 100%, and used distilled water as a negative control and ciprofloxacin as a positive control. The inhibition zone is determined by observing the clear zone.

Abstract

Dermatophytosis remains a common superficial fungal infection affecting nails and interdigital spaces, with Trichophyton rubrum and T. mentagrophytes as the predominant etiologic agents. The recent emergence of terbinafine-resistant T. indotineae has raised new challenges in diagnosis and treatment. Although Sabouraud Dextrose Agar is the conventional medium for fungal culture, alternative media such as Czapek Yeast Extract Agar (CYA) may provide additional advantages for dermatophyte isolation and morphological identification. This study aimed to isolate and identify dermatophytes from toenails and interdigital spaces of university students using CYA medium and to evaluate its applicability in dermatophyte culture. A cross-sectional descriptive study was conducted among 100 university students aged 18–24 years. Specimens were collected from toenails (n = 60) and interdigital spaces (n = 40). Direct microscopy was performed using 20% KOH preparation. Samples were cultured on CYA supplemented with chloramphenicol and cycloheximide, and incubated at 28 ± 2 °C for up to 21 days. Fungal isolates were identified based on macroscopic and microscopic morphology. Data were analyzed descriptively, and associations were tested using the chi-square test. Fungal elements were detected in 65% of samples by KOH examination, and dermatophyte growth was confirmed in 52% of cultures. The most frequently isolated species were T. rubrum (28%) and T. mentagrophytes (18%). Notably, T. indotineae was detected in 5% of samples. No significant difference was found between toenail and interdigital isolates (p = 0.26). Dermatophytes are prevalent among university students, with T. rubrum as the dominant species. The detection of T. indotineae highlights its emerging role in young populations. CYA proved effective for dermatophyte isolation and may serve as an alternative culture medium in academic and diagnostic laboratories.
