HUBUNGAN INDEKS BAKTERIOLOGIS SAYATAN KULIT DAN CUPING TELINGA DENGAN TITER ANTIBODI IgM ADNTI PGL-1 PADA PENDERITA KUSTA BAARU DI RSUD Dr. SOETOMO SURABAYA
"Leprosy is a disease caused by Mycobacterium ieprae, also known as
Hansen 's disease. Skin is the major area of infection manifestation, it can also
cause nerve damages that can lead to abnormalities or deformities, especially on
extremities. Laboratory diagnostic of leprosy is performed using microscope to
find acid fast bacilli by calculating Bacteriological Index (BI) and serologically to
examine anti PGL-I. This study will explore comparativeness between specimens
extracted from ear lobe against specimen from other body surface skin lesion. IgM
anti PGL-I will be a gold standard for diagnosis ofleprosy.
This study was performed on a new leprosy patients visited Department of
Skin and Venereology, Dr. Soetomo Hospital Surabaya, from October until
December 2007, by cross sectional approach. The aim of this study is to find out
correlation between BI and antibody IgM anti PGL-I titer. The specimens were
taken as follow: I) slit-skin from ear lobe and 2) slit-skin from lesion in the body
surfar ~ for Bacteriological Index examination; and 3) venous blood specimen for
examine antibody IgM anti PGL-I.
The results from 30 samples, 25 samples were leprosy patient MB type
and 5 sample patients PB type. All leprosy PB types had shows BI 0 score. About
44% leprosy MB type shows BI 0 score from the ear lobe specimens, while 24%
shows BI 0 score from the skin lesion specimens. The antibody IgM anti PGL-I
titer from ELISA test was range from 131 - >6300 ulml, 5 samples were found to
be the seronegatif «605 ulml), while the other 25 samples were seropositif (2':605
ulml). There is a significant correlation between BI ear lobe and BI skin lesion
with antibody IgM anti PGL-I titer. The significances for BI skin lesion with
antibody IgM anti PGL-I titer was r=0,580 (p=0,01) and for BI ear lobe with
antibody IgM anti PGL-I titer was r=0,566 (p=0,0 I). This fmding shows that there
are no differences between smear from skin lesion and ear lobe for diagnose of
leprosy.

Free Radical Scavenging and Analgesic Activities of 70% Ethanol Extract of Luvunga sarmentosa (BI.) Kurz from Central Kalimantan
Luvunga sarmentosa, commonly known as saluang belum, is widely used in Kalimantan to relieve pains, rheumatism, boost the immune system, and fever. The research on the free radical scavenging and analgesic effect of the L. sarmentosa stem extract has not been reported. This study aimed to evaluate the free radical scavenging and analgesic activity of the ethanol extract of L. sarmentosa. The L. sarmentosa stem was extracted using 70% ethanol and tested for free radical scavenging using the 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) and analgesic activity, acetic acid-induced writhing test, and hot plate test in an animal model. The results showed that the 70% ethanol extract of the L. sarmentosa had an anti-free radical scavenging and analgesic activity. The extract has weak free radical scavenging with an IC50 value of 293.45 µg/mL. Analgesic activity using the writhing test indicated that the extract significantly reduced the writhes count after oral administration in a dose-dependent manner compared to the negative control. Extract at a dose of 550 mg/kg BW can reduce the writhing test by 67.60% compared to others. In contrast, the diclofenac sodium reduced the number of writhes by 74.74%. While in a hot plate, the extract at a dose of 550 mg/kg BW produced a maximum possible analgesia (MPA) of 17.64%, lower than the MPA of diclofenac sodium (51.01%). Analgesic activity of the extract has higher inhibition on the writhing test than on the hot plate. The extract could be responsible for the peripheral mechanism by inhibiting the prostaglandin biosynthesis
Anti-viral activity of Phyllanthus niruri against hepatitis C virus
Hepatitis C virus (HCV) infection is a global problem that causes liver disease and hepatocellular carcinoma. Although the
current standard treatment provided a significant improvement on response rate with sustain virology response more than
90%, however, the high cost was remaining limited access to this therapy, resistance emergence and serious side effects
which provide the necessities to find the new anti-HCV agents. The current study, we evaluated the ethanol extract of Phyllanthus
niruri for its anti-HCV activities. Anti-HCV activity was determined by in vitro culture cells of Huh 7it. Anti-HCV activity
of P. niruri extract revealed strong inhibition against HCV with IC50 values of 4.14 µg/mL and yield stronger activity in the
entry step of the HCV life cycle. Moreover, the P. niruri extract enhanced anti-HCV activity of simeprevir (NS3 protease
inhibitor) with increase the activity up to 4-fold compared to a single treatment of simeprevir. Docking analysis was performed
to predict the interaction phyllanthin and hypophyllantin, known compounds of P. niruri against HCV receptor. Both of
phyllantin and hypophyllantin were mediated a strong interaction with 4GAG, a protein that involved in entry step of HCV.
These results suggested that the ethanol extract of P. niruri may be good candidates for the development of anti-HCV drugs
AntiHepatitis C Virus Activity of Alectryon serratus Leaves Extract
Hepatitis C Virus (HCV) has infected approximately 2-3% (130-170 million) of the world's population. No vaccine is available to prevent HCV infection. Investigation of anti-HCV agent is thus deemed necessary. Various plants have been explored for their anti-HCV activity. A. serratus is a member of Sapindaceae family, which fruit and seed were traditionally used as insecticide. Anti-HCV activity tested on A.serratus leaves extract has been done. The result showed that leaves extract exhibited anti-HCV with IC50 value of 14.9 μg/ml and 9.8 μg/ml against HCV J6/JFH1 and JFH1a, respectively. The cytotoxicity assay results showed that A.serratus leaves extract was not toxic and has CC50 >100 μg/ml. Mode of action experiment results suggested that A.serratus extract inhibited HCV at the post-entry step. Further fractionation of leaves extract by open column chromatography resulted in 4 fractions. Only Fraction 1 (AP-5F.1) exhibited anti-HCV with IC50 value of 1.2 μg/ml against HCV JFH1a. Separation of AP-5F.1 by open column chromatography resulted in 15 fractions. Fraction number 13 (AP-5F.1.13) exhibited anti-HCV with IC50 value of 0.43 μg/ml against HCV JFH1a. Separation of AP-5F.1.13 by semi preparative-HPLC resulted in isolate identified by TLC and LC-MS method as chlorophyll derivate. There was a possibility that chlorophyll derivate has participated in performing the anti-HCV activity of fractions and extract besides the other compounds contained. In this study, we concluded that A. serratus leaves extract, AP-5F.1, and AP-5F.1.13 exhibited anti-HCV activity against JFH1a virus
ANTIHEPATITIS C VIRUS ACTIVITY OF INDONESIAN MAHOGANY (TOONA SURENI)
 Objective: Toona sureni (Indonesian mahogany) is a member of Meliaceae family and locally known as suren. Previous study reported that T. sureni leaves extract exhibited antiviral activity with 50% inhibitory concentration (IC50) value of 13.9 ± 1.6 μg/ml against hepatitis C virus (HCV) J6/JFH1. Cytotoxicity analysis of T. sureni leaves extract did not reveal any cytotoxicity effect; therefore, further study was taken to investigate the active substances from the extract.Methods: Bioassay-guided isolation of anti-HCV was conducted using Huh-7.5 cells infected with HCV J6/JFH1 in the presence of extracts, fractions, or compounds from the plant.Results: Ethyl acetate fraction (Fr E) exhibited high anti-HCV activity with IC50 value of 1.7 μg/ml. Further, separation of Fr E by open column chromatography resulted in nine sub-fractions (sub-Fr E1-E9). Sub-Fr E3 and E4 have IC50 value of 29.90 μg/ml and 7.68 μg/ml, respectively. Polyphenols compounds have been isolated from sub-Fr E3 and E4. The structures have been determined to be ethyl gallate (1), methyl gallate (2), catechin (3), gallic acid (4), and quercetin 3-O-rhamnoside (5). Among the isolated compounds, gallic acid showed to possess strong anti-HCV activity with IC50 value of 15.9 μg/ml.Conclusion: T. sureni and its isolated compound, gallic acid, may be good candidates to develop for alternative and/or complementary agents of anti-HCV infection
Antiviral Activities of Indonesian Medicinal Plants in the East Java Region Against Hepatitis C Virus
Background
Hepatitis C virus (HCV) is a major cause of liver disease and a potential cause of substantial morbidity and mortality worldwide. The overall prevalence of HCV infection is 2%, representing 120 million people worldwide. Current standard treatment using pegylated interferon and ribavirin is effective in only 50% of the patients infected with HCV genotype 1, and is associated with significant side effects. Therefore, it is still of importance to develop new drugs for treatment of HCV. Antiviral substances obtained from natural products, including medicinal plants, are potentially good targets to study. In this study, we evaluated Indonesian medicinal plants for their anti-HCV activities.
Methods
Ethanol extracts of 21 samples derived from 17 species of medicinal plants explored in the East Java region were tested. Anti-HCV activities were determined by a cell culture method using Huh7.5 cells and HCV strains of 9 different genotypes (1a to 7a, 1b and 2b).
Results
Four of the 21 samples tested showed antiviral activities against HCV: Toona sureni leaves (TSL) with 50% inhibitory concentrations (IC50) of 13.9 and 2.0 μg/ml against the HCV J6/JFH1-P47 and -P1 strains, respectively, Melicope latifolia leaves (MLL) with IC50 of 3.5 and 2.1 μg/ml, respectively, Melanolepis multiglandulosa stem (MMS) with IC50 of 17.1 and 6.2 μg/ml, respectively, and Ficus fistulosa leaves (FFL) with IC50 of 15.0 and 5.7 μg/ml, respectively. Time-of-addition experiments revealed that TSL and MLL inhibited both at the entry and post-entry steps while MMS and FFL principally at the entry step. TSL and MLL inhibited all of 11 HCV strains of all the genotypes tested to the same extent. On the other hand, FFL showed significantly weaker inhibitory activities against the HCV genotype 1a strain, and MMS against the HCV strains of genotypes 2b and 7a to a lesser extent, compared to the other HCV genotypes.
Conclusions
Ethanol extracts of TSL, MLL, MMS and FFL showed antiviral activities against all the HCV genotypes tested with the exception that some genotype(s) showed significant resistance to FFL and to MMS to a lesser extent. These plant extracts may be good candidates for the development of anti-HCV drug
