Oxidatieve stress speelt een grote rol bij het verkrijgen van diabetes

Een onderzoek naar de werking van drie Ayurvedische kruiden.

Onderzoeken en klinische studies wijzen herhaaldelijk uit dat oxidatieve stress een grote rol speelt in de pathogenese van zowel diabetes mellitus type 1 als type 2. Oxidatieve stress leidt tot β-cel vernietiging door apoptosis. Door het zoeken naar een middel om oxidatieve stress te verminderen is strategisch gezien een goede insteek om beide type diabetes mellitus te behandelen.
Planten zijn een belangrijke bron van antioxidanten en hebben een beschermende effect tegen oxidatieve stress in biologische systemen.

Ayurvedische kruiden

De Indiase kruisbes (Phyllanthus emblica), kurkuma (Curcuma longa) en een klimplant (Tinospora cordifolia) zijn drie welbekende planten in de ayurveda die bekend staan om hun anti-hyperglycemische werking. Meerdere wetenschappelijke studies in vivo en in vitro bevestigen deze eigenschap.

In vitro onderzoek op cellijn vergelijkbaar met β-cellen

Drie Indiase onderzoekers Kalekar SA., Munshi RP. en Thatte UM. onderzochten de werking van deze drie kruiden in een test waarbij cellen van de cellijn RINm5F geinduceerd werden met streptozotocine (STZ). Streptozotocine is een stof die stress induceert. RINm5F is een cellijn die fungeert als model van de β-cellen uit de pancreas.

Parameters

Niet-toxische concentraties van plantenextracten werden geïdentificeerd met behulp van MTT assay. Lipideperoxidatie door MDA (Malondialdehyde) afgifte, modulatie van apoptose en afgifte van insuline waren de variabelen die werden gemeten om de door streptozotocine veroorzaakte schade en bescherming van de plantenextracten te beoordelen.

Op de rem

Alledrie de kruidenextracten vertoonde een significante rem op de vrijlating van MDA uit de RIN cellen. Dit toont onomstotelijk aan dat deze kruiden een beschermend effect hebben tegen STZ-geïnduceerde oxidatieve schade. Ze vertoonden een dosis afhankelijke anti-apoptotisch effect zoals te zien is bij een afname van de sub G0 populatie als reactie op STZ. Geen van de plantenextracten hadden een noemenswaardig groot effect op de afgifte van insuline uit de cellen.
