Seahorse (Hippocampus sp) is the unique fish, because the male is pregnancy. The seahorse not only given an economic value but also have a potential drug for medical use, which is have a steroid an aphrodisiac for fertility. The previous studies have reported the function seahorse extract and have been studied both in vitro and in vivo to know the effects from the natural product. Nowadays, infertility caused many factors, such as a factor from the male including spermatogenesis and testis disorder. In decade, there is the treatment for infertility used GnRH therapy, but it still controversy between the impact in reproductive system and needed the study. GnRH in vertebrate has a G receptor from kisspeptin gene to transcription promote and suggested a key regulator reproductive with a kiss 1 gene, which is the same function in mammals and fishes. In this condition, it is suggested a bioactive compound in seahorse can be investigated to replace a treatment infertility in male with GnRH therapy. It can be done through drug delivery systems with several carrier systems, such as nanoparticles. In the future, bioactive compound from seahorse needed the study to explore a potential drug in medical use including the efficiency and efficacy for fertility in human with nanotechnology approach.

Introduction: Male hormonal contraception known as safe, effective, and reversiblecontraception. World Health Organization (WHO) multicentre study has been conducted aclinical study administrating of testosterone regimens and progestin to male with a remarkableresult. Azoospermia or severe oligozoospermia occurred in men with injection of TestosteroneEnanthate (TE) and Depot Medroxyprogesterone Acetate (DMPA) as well as TestosteroneUndecanoate (TU) and DMPA for a longer period. Decreasing gonadotropin as well astestosterone could lead to the amount of spermatogenic cells population declining by suppressingthe development of many kinds of cells. This narrative review was to compare howspermatogenic suppression in TE and TU with Combination of DMPA. Method: We arerandomly select article or journal from several databases and individual journal in certainkeywords. The keyword used were : (male hormonal contraception) OR (regimen testosterone))AND (progestin) OR (DMPA) OR (Testosterone enanthate) OR (Testosterone undecanoate) OR(male hormonal contraception combination)) AND (DMPA to spermatogenic cells) OR(Testosterone and DMPA to germ cell development)). After initial searching from databases andindividual journal website, 16 scientific articles or journals selected for the review. Result: Theresult indicated that injection of TE and DMPA had suppressed spermatogenesis, might notsuppressed sperm production for a longer period but the decreasing in type B spermatogoniauntil pachytene spermatocyte did occur. On the other hand, injection of TU and DMPA couldmaintain the suppression of sperm production for a longer period due to sustainable higher serumMPA with combination to even longer-acting TU would have more profound effect for that.Conclusion: It was known that combination of TU and DMPA might have better suppression onsperm production than TE and DMPA, otherwise further research needs to be obtained from thecombination of TU and DMPA on spermatogenic development and the association withintratesticular testosterone.

Introduction: Epstein Barr Virus (EBV), a member of the Herpesviridae family, is a dsDNA virus. Nasopharyngeal carcinoma (NPC) patients express EBV latent genes EBERs, EBNA1, LMP1, LMP2A, and LMP2B. The LMP1 gene, in particular, plays important roles in epithelial oncogenesis and B-lymphocyte transformation. Several epidemiological studies found a specific variant of LMP gene detectable as a 30-bpdeletion in NPC patients and it is still unclear whether this deletion is associated with NPC pathogenesis in Indonesian population. The aim of this research is to understand the existence of the deletion of the 30-bp LMP1 gene in Indonesian NPC patients and to determine the frequency of 30-bp deletion of LMP1 gene and its association with the pathological status. Methods: The 30-bp deletion in LMP1 gene was identified by nested PCR and subsequent electrophoresis in 2% agarose gel. The results were determined as 162-bp DNA band of the LMP1 gene (without 30-bp deletion) and 132-bp DNA band of the LMP1 gene (with 30-bp deletion). Results: Among 100 identified samples from Jakarta, 8 samples were found to have the 30-bp deletion, 71 samples did not have 30-bp deletion and 21 samples carried coexistence variants. Conclusion: In Indonesia, especially in Jakarta, EBV variant of 30-bp deletion of LMP1 gene was found at low frequency (8%) in comparison with variant without deletion (71%). There is a variant of LMP1 gene mixtures (21% coexistence with and without deletion). Analysis of data using Fisher's exact test shows that there is no significant relationship between 30-bp deletion of LMP1 gene and NPC pathological status (p> 0.05).Key words: 30-bp deletion, NPC, EBV, LMP1, Coexistence

Effect of Injection Minimal Dosages of Depot Medroxyprogesterone acetate (DMPA) to Body Weight and Blood Chemistry Male Rat Strain Sprague-Dawley. Many family planning program focus more on men. Until now, vasectomy has been the commonly used method for male contraception. However, this method creates inconvenience such as irreversibility and psychological problems. One of the alternatives contraception is the combination of depot medroxyprogesterone acetate (DMPA) and androgen. The minimum dosage of DMPA could suppress testosterone level that leads to reduced spermatogenesis and sperm viability. Nevertheless, until now it is not known whether minimum dosages of DMPA have an effect to body weight and blood chemistry. Therefore, this research aimed at determinate the effect of minimal dosages of DMPA to body mass and blood chemistry using male rats (Rattus norvegicus L.) strain Sprague-Dawley as model. This research using completely randomized design, unequal size sample, castration treatments and several doses DMPA (1.25, 0.625, and 0.313 milligram). Injecting of DMPA conducted intramuscularly on week 0 and week 12. Normality/homogeneity Data normality were analyzed before ANOVA test. Then, abnormal data were tested using Kruskal-Wallis test. The result shows that injection of DMPA in various doses do not have an effect on body weight and blood chemistry such as erytrocytes, haemoglobin, hematocrite, HDL, LDL, total cholesterol, SGOT, SGPT and triglyseride) (p>0,05). Furthermore, it is concluded that that no effect of minimal dosages of DMPA to body mass and blood chemistry of rat.

The development of male hormonal contraception is based on a decrease in sperm concentration without affecting libido and sexual potency. The combination of depot medroxy progesterone acetate (DMPA) + extract of Javanese long pepper (JLP) with dosages of 0.94 mg and 1.88 mg decreases the concentration of spermatozoa. However, it remains unknown whether the combination influences body weight, hematology, and blood biochemistry. Therefore, it is necessary to investigate the effect of DMPA + JLP extracts on the body weight, hematology, and blood biochemistry of male rats (Rattusnorvegicus L.) using Sprague-Dawley strains. The research uses a completely randomized design (CRD); one group control and two treatment groups. In the first group, the castrated rats were given oral administration extracts of JLP (CJ) with doses of 0, 0.94, 1.88, 2.82, and 3.76 mg. In the second group, the rats were injected with 1.25 mg DMPA and given an oral administration extract of JLP. Injection was given in week-0 and 12. Administration was conducted every day from week 7-18. Analysis of the normality and homogeneity of data is done before the ANOVA test. Data that is abnormal and not homogeneous are tested with non-parametric statistical Kruskal-Wallis. This study shows that the combination of minimal doses of DMPA and administration variousdoses of extracts of JLP does not affect body weight and hematology (erythrocyte, hemoglobin, hematocrite), and the blood biochemistry of rats, such as the values of SGPT, SGOT, HDL, and triglycerides (p < 0.05), but rather the total cholesterol and LDL (p < 0.05). Furthermore, it is concluded that the combination of the minimal dosage of DMPA and weaned various dosages of JLP extracts affect the total value and LDL cholesterol but do not influence body weight, nor hematology and blood biochemistry. Such combinations can be drawn on for asafe male contraceptive model t by taking into account the value of the total cholesterol and LDL during its use.
