Laboratory mice (Mus musculus L.) were investigated for DDT induced chromosome mutations. Twenty-four brown and Balb/c strain albino mice were intraperitoneally injected with 25, 50, 100 and 250 ppm (mg/kg body weight) of DDT in peanut oil, and killed 48 h later. Controls received either no injection or peanut oil only. Karyotypes from bone marow cells of femurs were analyzed for gaps, deletions, and stickiness. Data for chromosome aberrations were taken from 200 well spread cells per animal, and mitotic indices were calculated from 1000 cells per animal. Regression of aberrations on log DDT concentrations, and Dunnett's multiple comparison test were employed to determine the effect of DDT treatments. Gaps, stickiness and mitotic indices were not significantly affected by DDT treatments, but deletions and gaps plus deletions were significantly higher or approached the significant levels at 50 ppm and higher concentrations. DDT thus appears to act as a mutagen in concentrations encountered naturally in many secondary consumers.

Effect Of Age

Adult animals have been used for most of the previous mammalian temperature selection studies, and relatively few systematic observations have been made with young animals. In this investigation, laboratory mice (Mus musculus), ranging in age from 1 to 84 days, were studied in a horizontal temperature gradient established along a 5-ft copper bar. Despite poorly developed locomotion and cold immobilization, it was shown that the temperature selection response is present at birth. The initially high level of selection appeared to be maintained for about 2 weeks, after which it began to decrease, rapidly at first, and then more slowly until the adult level was reached.

AbstrakIndonesia memiliki banyak tumbuhan berpotensi obat salah satunya bisa dijadikan sebagai obatkontrasepsi tradisonal yang biasa digunakan untuk menjarangkan anak atau sterilisasi sepertirebusan akar Caesalpinia bonduc (Aru). Tujuan penelitian untuk mengetahui pengaruh obatkontrasepsi tradisional air rebusan akar aru terhadap kualitas pematangan sperma epididimis mencit(Mus musculus). Mencit dipilih secara acak untuk mewakili 4 kelompok dosis yaitu : 0,0 (K0), 16,0(K1) 24,0 (K2) dan 32,0 (K3) μl/gram berat badan/hari. Setiap kelompok perlakuan dilakukandengan 5 kali replikasi. Perlakuan diberikan melalui oral dengan menggunakan jarum gavage selama10 hari berturut-turut. Pembedahan dilakukan pada hari pertama setelah perlakuan selesai.Pengamatan kualitas sperma epididimis dengan perhitungan produksi sperma, % sperm motil, %sperma hidup, % sperma abnormal,dan rangking keaktifan sperma. Untuk mengetahui ada atautidaknya perbedaan yang bermakna antar perlakuan dalam kelompok dilakukan uji Anava satu arah,bila terdapat perbedaan bermakna dilanjutkan uji BNJ untuk membandingkan angka rata-rata antarkelompok perlakuan. Pemberian air rebusan akar Caesalpinea bonduc pada mencit menunjukanpengaruh perbedaan secara signifikan pada jumlah (%) sperma abnormal antara dosis 0,0 μl dengan24,0 dan 32,0 μl serta antara 16,0 μl dengan 24,0 dan 32,0 μl; Jumlah (%) sperma hidup terdapatperbedaan antara dosis 0,0 μl dengan 16,0 , 24,0 dan 32,0 μl; Jumlah (%) sperma motil terdapatperbedaan antara dosis 0,0 μl dengan 24,0 dan 32,0 μl; Rangking keaktifan sperma terdapatperbedaan antara dosis 0,0 μl dengan 24,0 dan 32,0 μl. Pemberian rebusan akar aru berpengaruhsecara signifikan terhadap peningkatan persen sperma abnormal, dan penuruan persen sperma hidup,motil dan keaktifan.AbstractIndonesia has many species of plants that have potent of medicine, one of them cold be as antraditional contraception medicine ussually used to limit child or sterilizatiom such as root boiledwater of Caesalpinia bonduc. The aims of this study is to know the effect of root boiled water ofCaesalpinia bonduc as traditional contraception medicine on quality of sperm maturation ofepididymis of mice (Mus musculus). Mice were choosed radomly and doses gouped: 0,0 (K0 ), 16,0(K1) 24,0 (K2) and 32,0 (K3) μl/gram body weight/day. Each of group was replicated 5 times.Treatment were given by oral with using gavage needle for ten days. Surgery was carried out on firstday after completing treatments. Examination of epidymis sperm by counting number of spermproduction, percentage of motil, live, abnormal sperm, and rank of sperm motility. In order to knowthe deferences between control and treated group, was used one way anava analysis and analysedvalue for comparing between teratment group. The treatments of root boiled water of Caesalpiniabonduc have effect significantly on percentage of abnormal sperm between dose of 0,0 μl with 24,0and 32,0 μl, also between 16,0 μl with 24,0 and 32,0 μl. Percentage of live sperem is different betweendose of 0,0 μl with 16,0 , 24,0 and 32,0 μl. Percentage of motile sperm is defferent significantlybetween dose of 0,0 μl with 24,0 and 32,0 μl. Meanwhile percentage of motile rank has differencebetween dose of 0,0 μl with 24,0 and 32,0 μl. The treatment of root boiled water of Caesalpiniabonduc has effect signifiantly on increasing percentange of sperm abnormality, decreasingpercentage of life sperm, motile and rank of motile of mice sperm.

Cardamom is known as a plant with millions of benefits and it is known to contain aphrodisiac substances. The role of cardamom as an aphrodisiac need to be studied more deeply from the scientific point of view. The experimental object is a 3-month-old male white mice (<em>Mus musculus albinus</em>) with an average weight of about 30-35 grams. After being acclimatized for approximately 2 weeks, 35 mice were divided into 3 groups based on the dose of cardamom extract. At the end of the experiment, the mice will be sacrificed and then the testes were weighed and cauda epididymis were isolated to collect the sperm. Our findings suggested that the dose of administration has important role in affecting the weight of testes and bodies of mice. However, further studies on sperm profiles and optimal administration doses of cardamom extract are highly recommended.

The objective was to determine the effect of Brassica oleracea var Botrytis "cauliflower" inflorescences on cachectic syndrome in Mus musculus var. swiss with induced cancer. Cachectic syndrome is characterized by progressive loss of body weight, anorexia, asthenia, immunosuppression and metabolism of carbohydrates, lipids and proteins, with loss of muscle and adipose tissue. It used dry cauliflower inflorescence extract (ESC) and male mice 35-45 g with induced cancer, divided into groups: G1 untreated control, G2 and G3 treated with ESC, doses 10 and 20mg/kg/bw/vo and G4 treated with quercitin, dose 7.14mg/Kg/bw/vo for 90 days. Some manifestations of cachectic syndrome were determined. It was observed that G1 had thinning and progressive increase in alopecia, asthenia and conjunctival xerosis due to energy and metabolic imbalance compared to G2, G3 and G4 that had higher body weight and fewer cachectic manifestations, being significant by time and treatment group (P<0.01). It has been reported that cauliflower contains flavonoids quercitin and kaemferol, with anti-inflammatory properties for its action on cyclooxygenase, lipooxygenase, interleukins and chemosins, with antioxidant properties on intracellular glutathione, in redox reactions and favoring the expression of caspases in cell apoptosis. Therefore, it is concluded that cauliflower prevents body weight loss and decreases cachectic syndrome because it contains kaempferol and quercitin that act synergistically with anti-inflammatory, antioxidant and anticancer properties.
