Bengkuang merupakan salah satu tanaman obat yang berpotensi sebagai bioinsektisida. Penelitian ini bertujuan mengetahui efektivitas biji bengkuang sebagai insektisida nabati terhadap larva lalat Crysomya bezziana (C. bezziana) agen penyebab miasis secara in vitro. Penelitian ini terbagi menjadi 5 kelompok perlakuan. Masing-masing sebanyak 20 Larva instar 1 (L1), Larva instar 2 (L2), dan Larva instar 3 (L3) C.bezziana digunakan untuk pengujian in vitro menggunakan pot plastik yang berisi media larva dan ekstrak ethanol biji bengkuang dengan konsentrasi bertingkat 0,06, 0,12, dan 0,25%. Coumaphos 0,06% dan akuades steril digunakan sebagai kontrol positif dan negatif. Hasil penelitian menunjukkan bahwa pada konsentrasi 0,25% mampu menyebabkan 100% kematian larva dan 100% pupa tidak menetas. Pengujian L3 menunjukkan bahwa ekstrak ethanol biji bengkuang mampu menyebabkan penurunan daya tetas pada semua konsentrasi. Pengujiaan L1 dan L2 untuk mengindikasikan efektifi tas ekstrak sebagai racun perut, sedangkan pengujian pada L3 sebagai indikasi racun kontak. Biji bengkuang memiliki daya larvasida terhadap beberapa jenis larva serangga C. bezziana.
Previous in vitro studies showed that nanoparticle extract of turmeric, zedoary, and garlic exhibit antibacterial activity against Mycoplasma gallisepticum (M. gallisepticum) which causes chronic respiratory disease (CRD) in chicken. This research aimed to determine the antibacterial activity of nanoparticles of Curcuma longa, Curcuma zedoaria, and Allium sativum extract to CRD infected chicken. In vivo test of antibacterial activity of turmeric, zedoary, and garlic nanoparticle in combination was conducted on chicken infected by M. gallisepticum and Escherichia coli (E.coli). Antibiotic control used was enrofloxacin. As many as 75 chickens were divided into 5 groups containing 15 chickens each. Group one consisted of healthy chickens (positive control); group two consisted of chickens that have been inoculated by bacteria (negative control); group three (treatment) were chickens inoculated by bacterium and given extract nanoparticle combination on day 7 of infection for 7 days; group four (prevention) were chickens inoculated by bacterium and given combination of extract nanoparticles on day 5 before infection for 14 days; group five were chickens inoculated with bacterium and given enrofloxacin antibiotics for 7 days. In vivo research results showed increased body weight and performance indicated by improvements in clinical signs, and gross pathology changes. The combination of three extract nanoparticles showed the best activity in controlling CRD in chicken, both as preventive and curative means.
Penelitian ini bertujuan mengetahui pengaruh pemberian simplisia daun bangun-bangun (Coleus amboinicus Lour.) terhadap gambaran darah dan marker stres (rasio H/L) ayam pedaging. Sebanyak 60 ekor ayam pedaging strain Cobb berumur 1 hari (DOC) dibagi ke dalam rancangan acak lengkap yang terdiri atas 4 perlakuan dan 15 ulangan. Ayam percobaan yang diberi tambahan simplisia daun bangun-bangun dalam air minum dengan dosis 0% (kontrol) dan dosis 0.125, 0.25, dan 0.375% (perlakuan). Pemberian perlakuan dilakukan selama 28 hari secara per oral melalui air minum yang dimulai sejak ayam berumur 8 sampai dengan 35 hari. Analisis darah dilakukan pada masing-masing kelompok perlakuan sebanyak 6 kali. Pengambilan sampel darah dilakukan pada hari ke-7 (sebelum perlakuan) dan 35 (setelah perlakuan). Hasil gambaran darah merah (jumlah butir darah merah, hematokrit, dan hemoglobin) dan diferensial darah putih (monosit, eosinofil, basofil) tidak berbeda nyata (p>0.05) pada semua perlakuan baik sebelum dan setelah perlakuan. Setelah perlakuan, ayam yang diberi daun bangun-bangun dosis 0.125 dan 0.25% memiliki rasio H/L yang lebih rendah dibanding kontrol (p<0.05). Hal ini mengindikasikan bahwa pemberian daun bangun-bangun dosis 0.125 dan 0.25% mampu menurunkan tingkat stres ayam percobaan tanpa disertai perubahan gambaran darah.
Objectives: The aim of this research is to study duck eggwhite potential in treating subacute lead poisoning.
Methods:The potential of duck egg white was evaluated from the red blood cell profile and the clinical signs that emerged. The research used thirty male rats which were divided into 6 groups and 5 replications (i.e. rats as control, rats administrated only with lead, rats administrated with lead and antidote). Each of the four treatment groups were given one antidote (i.e. EDTA, 50% egg white, 75% egg white, and 100% egg white). Lead force feeding was conducted for 15 days, followed by the administration of the antidote for the same duration of 15 days, and concluded with blood sampling at the end of each treatment.
Results:There was no significant effect on haemoglobin but lead decreased total red blood cells (p<0.05) in subacute lead poisoning. Rats that were given 75% and 100% duck egg white as an antidote showed an increase in total red blood cell counts in addition to a faster recovery.
Conclusion:High concentration of duck egg white had shown positive results as an antidote for subacute lead poisoning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
