ABSTRACT
The salivary gland secretion of the
haematophagous animals, leeches, has attracted the attention of therapists
since the extreme old ages due to its wide range of medical properties. Thus,
many researches have been done to develop and optimize new methods to collect
leech saliva with high quality and quantity. In the present study, we aimed to
evaluate the effects of starvation period and repeated collection on the
quality and quantity of leech saliva extract LSE and its contents of
proteins during the rainy season. Protein recovery in the LSE was also studied
after first collection. It was found that leeches are able to produce
protein-containing saliva whenever fed during the whole study period of 18
weeks with varied protein concentrations. The results showed that the highest
protein concentrations (105-91 μg/mL) were produced after
12-15 weeks of starvation. The results of successive collection showed that
leeches are able to produce proteins and peptides whenever they suck the
solution after first collection with some varies in the concentrations. The concentrations
varied between 0 and 72% of the initial concentration. Gel electrophoresis
results showed absence for some bands when the concentrations are too low. Also
the results showed that leeches are able to recover about 42% of their initial
proteins concentration within four weeks of starvation after first feeding. The
gel electrophoresis results showed the closeness between the first and second
collections. To conclude, all test factors (starvation period, successive
collection and recovery test) were shown to have an important impact on protein
concentration of leech saliva and therefore its medicinal affectivity. The
mentioned results are reported for the first time and they open the gate for
further studies.

ABSTRAK
Rembesan kelenjar air liur haiwan hematofaj,
lintah, telah menarik perhatian ahli terapi sejak dulu kerana pelbagai sifat
perubatan. Oleh itu, pelbagai kajian telah dijalankan untuk membangun dan mengoptimumkan
kaedah baru untuk mengumpul air liur lintah dengan kualiti dan kuantiti yang
tinggi. Dalam kajian ini, kami ingin menilai kesan tempoh kebuluran dan kutipan
ulangan pada kualiti dan kuantiti air liur lintah ekstrak LSE dan kandungan
proteinnya semasa musim hujan. Pemulihan protein di LSE itu juga dikaji
selepas kutipan pertama. Didapati bahawa lintah boleh menghasilkan protein yang
mengandungi air liur pada bila-bila masa setelah diberi makan sepanjang tempoh
keseluruhan kajian selama 18 minggu dengan kepekatan protein yang berbeza-beza.
Hasil kajian menunjukkan bahawa kepekatan protein tertinggi (105-91 μg/mL) telah dihasilkan selepas 12-15
minggu kebuluran. Hasil kejayaan kutipan menunjukkan bahawa lintah boleh
menghasilkan protein dan peptida pada bila-bila masa mereka menghisap larutan
selepas kutipan pertama dengan kepekatan berbeza. Kepekatan awal berbeza-beza
antara 0 dan 72%. Hasil gel elektroforesis menunjukkan ketiadaan jalur apabila
kepekatan terlalu rendah. Keputusan juga menunjukkan bahawa lintah mampu untuk
memulihkan kira-kira 42% daripada kepekatan protein awal dalam tempoh empat
minggu kebuluran selepas makan yang pertama. Keputusan gel elektroforesis
menunjukkan kehampiran antara kutipan pertama dan kedua. Kesimpulannya, semua ujian
faktor (tempoh kebuluran, kejayaan kutipan dan ujian pemulihan) telah terbukti
mempunyai kesan penting ke atas kepekatan protein air liur lintah dan kesan
perubatannya. Keputusan ini dilaporkan buat pertama kali dan membuka peluang
untuk kajian lanjutan.
