[Effect of vitamin E and thymalin on the development of experimental allergic encephalomyelitis].

Vilkov. G A GA; Stepanenko. E M EM; Kryzhanovskiĭ. G N GN

In rats that normally resist a brain‑immune disease, lacking vitamin E made them sick, but giving them the peptide thymalin stopped the illness. In guinea‑pigs that are prone to the disease, a combo of vitamin E (alpha‑tocopherol) and thymalin also blocked it. The study suggests that strong cell‑membrane antioxidants and healthy T‑cell immunity protect against this kind of autoimmune attack.

[Nonspecific and antigen-specific adhesiveness of circulating lymphocytes in dysentery patients undergoing combined therapy using thymalin and indomethacin].

Mats. A N AN; Cheprasova. E V EV; Elkina. S I SI; Koriakin. E V EV

In a study of dysentery patients, taking the anti‑inflammatory drug indomethacin helped the immune cells return to normal stickiness faster, while the thymus‑derived peptide thymalin didn’t change this. However, indomethacin also blocked the ability of T‑cells to stick to the specific bug (Shigella), which is part of a targeted immune response, and thymalin didn’t cause this block.

[Effect of thymalin on the status of immunogenesis and hemostasis in patients with ischemic heart disease].

Kuznik. B I BI; Budazhabon. G B GB; Sytnikova. I A IA; Morozov. V G VG; Khavinson. V Kh VKh

In a study of heart‑disease patients, adding the peptide thymalin to standard treatment helped bring immune markers back to normal, slowed down blood clotting, lowered fibrinogen and FDP levels, boosted the body’s ability to break down clots, and made chest‑pain episodes disappear faster than in patients who didn’t get the peptide.

[Age- and sex-related differences of neuroendocrine center reactions in the hypothalamus on preparation thymalin and alpha-tocopherol acetate].

Kozak. M V MV; Teplyĭ. D L DL

In rats, the peptide Thymalin and vitamin E (alpha‑tocopherol) affect brain areas that control hormone release. Young rats showed fewer active neurons in the arcuate nucleus after stress or vitamin E, while older rats were less responsive. Thymalin seemed to make the arcuate nucleus more sensitive to stress, lowering the threshold for activation.

[Use of thymalin in the complex treatment of patients with cancer of the uterus].

Bakhidze. E V EV; Bokhman. Ia V IaV; Khavinson. V Kh VKh; Morozov. V G VG

A small study of 21 women with uterine cancer added the peptide thymalin to their cancer treatment and saw a noticeable boost in T‑cell immune activity, suggesting it might help correct immune problems when T‑cell levels are tracked.

[Use of thymalin in trauma patients].

Gurevich. K Ia KIa; Khavinson. V Kh VKh; Morozov. V G VG

A small study gave the peptide thymalin to 23 people with serious injuries and found it helped lower infection rates, speed up recovery, and bring immune system markers back to normal. The results are promising but limited, so it’s not a proven protocol yet.

Utility 2

Expression features of T-lymphocytes, B-lymphocytes and macrophages in the post-traumatic regenerate of the mandible rats under conditions of filling a bone defect with hydroxyapatite-containing osteotropic material and thymalin injecting the surrounding soft tissues.

Boiko. Andrii A AA; Malanchuk. Vladislav A VA; Myroshnychenko. Mykhailo S MS; Markovska. Olena V OV;...

In a rat study, injecting the peptide thymalin into the soft tissue around a jaw bone defect that was filled with a hydroxyapatite bone graft boosted local immune cells (T‑cells, B‑cells, and macrophages) and shifted macrophages toward a healing (M2) type. This immune boost was linked to better bone repair in the rats.

[Use of thymalin in the complex treatment of frostbite].

Sizonenko. V A VA; Budazhabon. G B GB; Kuznik. B I BI; Khavinson. V Kh VKh; Morozov. V G VG

In a small study of 19 frostbite patients, adding the peptide thymalin to treatment helped the immune system work better, lowered blood clotting, increased the breakdown of clots, improved wound healing, and reduced infections.

[Effect of thymalin on the function of the blood kallikrein-kinin system in thymectomized rats].

Kiselev. V I VI; Kuznik. B I BI; Kurasov. V N VN; Treshchutin. V A VA; Morozov. V G VG

In rats without a thymus, the blood’s kallikrein‑kinin system gets over‑active, which could affect inflammation and blood pressure. Giving them the peptide thymalin brings the system back to normal levels, suggesting the peptide can regulate this pathway after thymus loss.

[Use of thymalin and kontrikal in the treatment of patients with injuries of the abdominal organs].

Salamatin. B N BN; Kravets. V N VN; Tarelkina. M N MN; Seĭfetdinov. E A EA; Sikora. L A LA; Ge...

The study says that giving the peptide thymalin (along with another drug called kontrikal) to people with serious belly injuries seemed to help their immune system recover, lower harmful gut bacteria in the blood, and cut the death rate from peritonitis. However, the paper doesn’t give details on how much was used or how the experiment was done, so it’s hard to turn this into a clear DIY protocol.

[Thymic factors influence on melatonin-producing pineal function in mice of different age: the possible mechanisms].

Labunets. I F IF

In adult mice, a single shot of the peptide mix called thymalin briefly raised blood melatonin levels after 3 hours and lowered them after 24 hours. This boost was linked to higher thymic factor (FTS) and lower stress hormone (corticosterone) and seemed to work better in certain seasons. The same treatment didn’t help older mice, even though their FTS went up.

[Morphofunctional state of organs of immunogenesis and adrenal glands after administration of a thymus preparation (thymaline)].

Khmel'nitskiĭ. O K OK; Belianin. V L VL; Grintsevich. I I II; Katsers. A R AR; Morozov. V G VG

In a mouse study, giving thymalin (a thymus extract) under the skin for ten days made the thymus work better, didn’t strongly boost the movement of immune cells into lymph nodes, and seemed to lower the activity of the adrenal glands that produce stress hormones. The results are from healthy mice and use injections, so they don’t directly tell us how to use thymalin in people.

[Effect of thymalin on blood coagulation and fibrinolysis].

Kuznik. B I BI; Budazhapova. D Ts DTs; Zagrebina. L A LA; Morozov. V G VG; Khavinson. V Kh VKh

In a small cat study, giving the peptide thymalin (2 mg daily for five days) made the blood break down clots faster after a clot‑forming challenge, compared to cats that didn’t get the peptide. The experiment showed an early spike in clotting followed by a later drop, and thymalin seemed to boost the later clot‑breakdown phase.

[Effect of thymalin and heterotransfusion on blood coagulation and fibrinolysis in thymectomized rats].

Kuznik. B I BI; Tsybikov. N N NN; Pisarevskaia. L I LI; Morozov. V G VG; Khavinson. V Kh VKh

In rats without a thymus, blood tends to clot too much and break down clots too slowly. Giving them the peptide thymalin for a week fixed these problems and helped their blood respond normally to a blood transfusion. This shows thymalin can balance clotting and clot breakdown in this animal model.

[Imbalance of T lymphocyte subpopulations in patients with psoriasis and its immune correction].

Rubins. A J AJ; Mashkilleysson. A L AL; Merson. A G AG; Gipsh. N M NM

The study looked at people with psoriasis and found many had an off‑balance between two types of immune cells (helper and suppressor T‑cells). In a tiny group, adding the peptide thymalin (along with another compound) helped fix this imbalance and the skin rash got better in most cases. The results suggest thymalin might aid immune correction in severe psoriasis, but the evidence is very limited.

[Changes in the histologic structure of the organs of immunogenesis during treatment with immunomodulators].

Khmel'nitskiĭ. O K OK; Morozov. V G VG; Khavinson. V Kh VKh

In a study on healthy animals, the thymic peptide thymalin and the bone‑marrow peptide hemalin were compared with the drug levamisole. Hemalin caused bigger changes in the main immune organs than levamisole, while all three substances affected the peripheral immune organs in a similar way. The findings are mostly basic science and don’t give clear guidance for human use.
