Abstract

Head lice is a major public health problem worldwide. Its treatment is challenging due to product failures resulting from rapidly emerging resistance to existing treatments, incorrect treatment application, and misdiagnosis. Various head lice treatments with different mechanisms of action have been developed and explored over the years, with limited reports on systematic assessments of their efficacy and safety. The head lice shampoo currently in circulation is 1% permethrin-based. Side effects of using permethrin-based shampoos include skin irritation and high resistance. The research conducted aims to present strong evidence that the use of shampoo made from bangle rhizome extract against head lice mortality is safer to use. The study used 240 head lice taken from elementary school students aged 8-12 years in a school in Bekasi. The study group was divided into 6 groups: negative control group (using baby shampoo), positive control group (using permethrin-based anti-lice shampoo), shampoo treatment group made from bangle rhizome extract with dose of 0.5%, 1%, 2% and 4%. In addition to calculating the number of head lice deaths per group, the time of death was also calculated to determine LC50 (Lethal Concentration 50), LC90 (Lethal Concentration 90), LT50 (Lethal Time 50), and LT90 (Lethal Time 90). The results showed a highly significant difference between the number of head lice deaths in the control group and the shampoo treatment group made from bangle rhizome extract (p<0.01). Likewise, there was a highly significant difference for the time of death of head lice in the control group and the shampoo treatment group made from bangle rhizome extract. Statistical analysis showed LC50 of 0.96%, LC90 of 2.84%, LT50 of 57.72 minutes, and LT90 of 28.79 minutes. It can be concluded that the effective dose of shampoo made from bangle rhizome extract is 4%, which can kill 100% of head lice within 27 minutes.

Abstract

Pyrethroid pesticide poisoning cases in developed and developing countries have a high incidence every year. One of the pyrethroid active substances that is widely used as an ingredient in anti-human lice shampoo (Pediculus humanus capitis) is permethrin 1%. The poisoning effect of permethrin-based shampoo as an anti-lice shampoo has been little studied, and there is a need to find alternative active ingredients from plants as a substitute for 1% permethrin, namely bangle (Zingiber montanum). The purpose of this study was to determine the toxicity of using shampoo made from 1% permethrin and made from bangle rhizome extract with graded doses through changes in kidney histopathology. The type of research was post test only control complete randomized design using 25 male mice, which were randomly divided into 5 groups, namely negative control (baby shampoo), positive control (1% permethrin shampoo), shampoo treatment made from bangle rhizome extract with graded doses (0.5%, 1%, and 2%). The shampoo was applied topically on the head for 14 days. After the mice were sacrificed, the kidneys were processed into tissues by paraffin method and stained with HE. Renal tubular injury was examined using a 400x magnification light microscope. The results showed the average changes in kidney histopathology in mice treated with 1% permethrin shampoo and 2% bangle rhizome extract shampoo, although not significantly different (p>0.05). Histopathological changes in the kidneys of mice that were seen were fatty degeneration which caused swelling of the proximal tubules and necrosis of kidney cells

Abstract

Caenorhabditis elegans is a microscopic nematode, with a transparent body, short life span, self-fertilization ability. C. elegans is easy to be cultured and has been used as an animal model for molecular research, medicine, pharmacology, and toxicology. In addition, C. elegans was the first animal to have its genome completely sequenced and has played a major role in understanding apoptosis and RNA interference. The use of C. elegans as a biological model in environmental toxicology assessments has allowed for the determination of several endpoints. Some of these utilize effects on the biological functions of the nematode and others use molecular markers. Furthermore, C. elegans has enabled the assessment of neurotoxic effects for pesticides and heavy metals, since this nematode has a very well-defined nervous system. Overall, almost every known toxin has been tested in this animal model. In the near future, the knowledge available about the life cycle of C. elegans will allow for more studies on reproduction, transgenerational toxicity for newly developed chemicals and materials, and detailing the signaling pathways involved in the mechanisms of toxicity. C. elegans is an important animal model for research into the identification and understanding of the machinery of nuclear transport. This has helped elucidate biochemical pathways involved in diseases such as obesity, diabetes, and Alzheimer's disease. C. elegans is an excellent animal model for studying aging because of its short lifespan, susceptibility to oxidative stress, and similarity to the human aging process.

Abstract

Pyrantel pamoate, known as an anthelmintic under the brand name Combantrin®, is effectively used to kill worms in the intestines. However, long-term use of it has been associated with side effects and risk of drug resistance. Syzygium cumini L.is known for its antioxidant and anti-inflammatory which may support antiparasitic effects and tissue healing. This study aims to examine the effect of juwet (S. cumini L.) fruit water extract (JFWE) on the duodenum structure of mice suspected to be infected with worm, through histomorphometric analysis and histopathological examination. The pyrantel pamoate was only administered once after the acclimatization period, while the JFWE was administered for 3 weeks. A total of 30 male mice were divided into six groups: negative control (aquadest), positive control (pyrantel pamoate, Combantrin® 20 mg/mL), and JFWE at doses of 5 mg/mL, 10 mg/mL, 20 mg/mL, and 40 mg/mL, administered for 3 weeks. Histomorphometric and histopathological evaluations were conducted by microscopically observing the duodenum structures, including intestinal villi, and the thickness of the mucosa, submucosa, and muscularis layers. The results showed a significant difference for the decrease in intestinal villi height and thickness of the mucosa, submucosa, and muscularis layers in JWFE doses of 5 mg/mL and 10 mg/mL administration group, compared to the negative control group (aquadest), the treatment groups of pyrantel pamoate, and JFWE doses of 20 mg/mL and 40 mg/mL (p<0.05). The conclusion is that the administration of juwet fruit water extract doses of 20 mg/mL and 40 mg/mL can improve the histomorphometry structure and also the histopathology of the duodenum of male mice.

Abstract

The juwet fruit (Syzygium cumini) is a type of fruit commonly found in Indonesia and is known to contain high levels of antioxidant compounds, potential for protecting reproductive organs from oxidative damage. This study aims to investigate the effects of juwet fruit in protecting the testes from damage caused by CCl4 toxicity in mice. A total of 30 mice were used and divided into six groups: distilled water, 12.5 mg/mL CCl₄, and S. cumini extract at doses of 5, 10, 20, and 40 mg/mL for three weeks.  Parameters assessed included body weight, serum testosterone levels, sperm count, and histomorphometry (seminiferous tubule diameter, germinal epithelium height, and spermatogenic cell counts). The results showed that CCl₄ significantly reduced body weight, the number of spermatogenic cells in the seminiferous tubules, seminiferous tubule diameter, germ cell height, and serum testosterone levels in the mice. The treatment groups receiving extract of juwet fruit at doses of 20 mg/mL and 40 mg/mL showed improvements in testicular function that were not significantly different from the distilled water group. In conclusion, reproductive toxicity induced by CCl₄ in male mice can be ameliorated by administering aqueous extract of juwet fruit at doses of 20 mg/mL and 40 mg/mL.
